You only need to know that 1mol means that the substance has na molecules, and na is about equal to it, especially the definition of the molar volume of the gas is in the standard state, and the 1mol gas is about, note that it must be in the standard state!
Just keep that definition in mind. On the first floor, be kind!
Moore's theorem is not too clear, anyway, the college entrance examination does not test the definition, unless you want to study chemistry or physics in college, you only need to know that 1mol means that the substance has na molecules, and na is about equal to it, especially the definition of the molar volume of gas, is in the standard state, 1mol of gas is about, especially pay attention to the standard state This condition must not be less, and the college entrance examination questions often have multiple-choice questions to test this.

The mass possessed by a substance as a unit of substance is called molar mass, which is denoted by the symbol m. When the mass of a substance is measured in grams, the unit of molar mass is g mol, which is numerically equal to the relative atomic mass or relative molecular mass of the substance. For a pure substance, its molar mass is fixed, while the mass of the substance varies with the amount of matter of the substance.

Moore's Law was proposed by Gordon Moore, one of the founders of Intel. The content is: when ** is unchanged, the number of transistors that can be accommodated on an integrated circuit will double every 18 months, and the performance will also be doubled.
In other words, the performance of a computer that can be bought for every dollar will more than triple every 18 months. This law reveals the speed at which information technology is advancing.

Moore's Law. It was Gordon Moore, one of the founders of Intel.
At the heart of the experience is that the number of transistors that can fit on an integrated circuit rubber doubles approximately every 18 months. In other words, the performance of the processor doubles every two years.
Moore's Law is the experience of the expert Moore, and the Chinese translation is called "law", but it is not a law of natural science, which reveals the speed of information technology progress to a certain extent.
To sum up, there are three main "versions" of "Moore's Law":
1. The number of circuits integrated on integrated circuit chips doubles every 18 months;
2. Microprocessor.
The performance doubles every 18 months, while the performance of Liang Fengbei decreases by half;
3. The performance of a computer that can be bought for a dollar quadruples every 18 months.

Moore's Law. Examples of chemical formulas:
Because m(nacl)=,m(nacl)=, we get n(nacl)=m m=. So according toEquationsGotta be thisChemical reactions2NaCl is and 2HCl is also because the coefficient ratio is the same.
Other Formulas for the Transformation of the Moore's Crack Law:1. The amount of matter.
Number of particles Avogadro's constant.
n=n/na);
2. The quantity of the substance = the mass of the substance The molar mass of the substance.
n=m/m);
3. The amount of matter = the volume of the gas sock body and the molar volume of the gas (n = v vm);
4. Foolish c = 1000 m.

Problem description: Actually, I know a little bit about this law, and I want to ask why he said that 18 months is 18 months.
In the end, did he stipulate this law or did it exist objectively? It's just that he discovered this pattern? I'm confused.
Analysis: Moore's Law" is based on Gordon, the founder of Intel Corporation. Moore's name is named after the word bent.
Gordon. Moore believes that the power of the processor doubles every 18 months. Over the past few decades, computers, especially microcomputers, their microprocessors, and many new technologies have developed at a rate that follows Moore's Law.
Moore's Law has now been "transplanted" to many new areas, such as coal propagation. The development of inter is also believed to follow the law of Moordine's law of ruin.
Generally speaking, if the same specification of IC is produced under the same area of wafer, with the advancement of process technology, the IC output can be doubled every other year, which is converted into cost, that is, the cost can be reduced by 50% every other year and a half, and the average annual cost can be reduced by more than 30%. By extension of Moore's Law, IC technology advances by a generation every year and a half.
This 18-month statement, in fact, Moore himself admitted that he did not say it.
According to the above method of calculating costs, this 18 months is objective, but Moore summarizes it and draws conclusions. At first, it wasn't what many people believed.
Moore's Law should be a kind of goal! It should be a strong psychological suggestion! , I don't think the law works! >>>More
