Anonymous users2024-02-11To be honest, there are no largest compounds, and now it is possible to synthesize some organic polymers, and the molar mass is many in the tens of thousands or even larger. So there is no maximum molar mass of the compound. Elemental substance has.

Anonymous users2024-02-10Nucleic acid DNA can reach one billion g per mole, but the molar mass of different nucleic acids varies greatly.
The molecular weight of synthetic polymer compounds is usually distributed in a wide range, and it is difficult to say whether there must not be a molecule larger than DNA (the larger the molecular weight, the smaller the probability, the extremely large molecular weight, and the extremely small probability of existence, but it cannot be asserted that it must not exist).

Anonymous users2024-02-09There is really no way to solve this problem of yours, because some polymer compounds are more than thousands, and the molar mass of different molecules of the same polymer compound is different, but there is an average value, and it is synthesized by different methods, and its molar mass is also different.

Anonymous users2024-02-05Summary. No, molar mass in physics refers to the mass of 1 mol of matter, while molar mass in chemistry refers to the mass of 1 mol of matter. Thus, molar mass in physics and molar mass in chemistry are different concepts.
Molar mass in physics refers to the mass of 1 mol of a substance, while molar mass sensitive band in chemistry refers to the mass of a 1 mol substance. Therefore, the quality of Moore in physics and the molar mass in chemistry are different concepts.
I'm sorry I don't understand, but can you elaborate on that?

Anonymous users2024-02-04A common substance is a molar mass possessed by a substance.
The mass possessed by a substance as a unit of substance is called molar mass, which is denoted by the symbol m. When the quantity of a substance is measured in mol, the unit of molar mass is g mol, which is numerically equal to the atomic mass or molecular mass of the substance. For a compound, its molar mass is fixed.
The mass of a substance changes with the amount of matter.
The quantity of matter is a physical quantity, which represents a collection containing a certain number of particles, and the symbol is n. The unit of quantity of a substance is moles (mol). Scientifically, the collective containing Avogadro's constant (about a particle as a unit, called mole.
The number of particles contained in 1mol of different substances is the same, but the mass of 1mol of different substances is also different due to the different masses of different particles.
It can be used to measure a specific combination of microscopic particles, for example, to measure the amount of sulfuric acid in moles, i.e. 1 mol of sulfuric acid contains one sulfuric acid molecule. Molar is the most widely used unit of measurement in chemistry, such as the calculation of chemical reaction equations, calculations in solutions, preparation and dilution of solutions, calculations of chemical equilibrium, gas molar volume and thermochemistry are inseparable from this basic unit.
Molar mass is the mass of a substance divided by the amount of matter in grams per mole, and molar volume is the volume of a substance divided by the amount of matter in cubic meters per mole. The gram atomic weight, gram molecular weight, and gram molecular volume, which were commonly used in the past, should be abolished.
Molar mass and molar volume are the derived quantities of the quantity of a substance, and the basic unit must be specified when applied, and the molar mass and molar volume are different for different basic units specified for the same substance.

Anonymous users2024-02-03Molar mass refers to the mass of one mole of substance. The unit is: g molThe molar mass of the substance, etc.
For the formula of this substance, the molecule is its molecular weight, and the atom is its atomic weight.......
For example, the molecular weight of sulfuric acid is 98, then the molar mass of sulfuric acid is, 98g mol
The atomic weight of iron is 56, then the molar mass of iron is, 56g molThe quantity of such a substance is not equal to the molar mass. The amount of matter is equivalent to a few moles in the unit:
Mole (mol). For example, the molar mass of sulfuric acid is 98g mol, and what is the amount of substance in 49g of sulfuric acid?
Calculation: n=49 98=
Generally, n is used to represent the amount of substance.
Covalent compounds are compounds that form covalent bonds between atoms. >>>More
A compound made up of cations and anions. When active metals (such as sodium, potassium, calcium, magnesium, etc.) and active nonmetals (such as fluorine, chlorine, oxygen, sulfur, etc.) are combined with each other, the active metals lose electrons to form positively charged cations (such as Na+, K+, Ca2+, Mg2+, etc.), and active nonmetals obtain electrons to form negatively charged anions (such as F-, Cl-, O2-, S2-, etc.), and cations and anions form ionic compounds by electrostatic action. For example, sodium chloride is an ionic compound composed of positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-). >>>More
The general formula of oxygenated acid can be written r-o-h like this, the easier it is to lose h, the more acidic it is. It depends on the force of the r-o side on h. The above three acids are the substitution of acetic acid in the two positions, only F, Cl and H are not the same, F and Cl have a certain electron withdrawing effect, but the F radius is smaller than Cl, and the electron withdrawing effect is larger than Cl, so the electrons are biased towards the R group, which reduces the electron cloud density on O, so that H is easier to remove, so the acid replaced by F is more acidic. >>>More

MNO2 is an amphoteric oxide.
When the reducing agent is encountered, it is oxidizing. For example, manganese dioxide is heated to 1400K in a hydrogen gas stream to obtain manganese monoxide; Manganese dioxide is heated in an ammonia gas stream to obtain brown-black manganese trioxide; Manganese dioxide is reacted with concentrated hydrochloric acid to obtain manganese dichloride and chlorine gas. >>>More
