How many nanometers is 500 daltons?

Dalton is a unit of relative atomic mass. Can't be converted into nanometers.

The relative atomic mass can also be directly expressed by 1 For example, the relative atomic mass of hydrogen is 1 dalton, or it can be directly expressed as 1. Although atoms are very small particles, they still have a certain mass. Atoms have different masses. If the mass of atoms is expressed in kilograms, it will be too big. Therefore, we call the mass of a carbon atom (called carbon 12, with 6 protons and 6 neutrons in the nucleus) 12 dalton. Law of partial pressure of gas

In addition, Dalton's contribution to meteorology and physics is also outstanding. He is a meteorological fan. He observed the weather continuously from 1787 until a few hours before his death, and kept a weather diary of about 200,000 words. 180 1 also puts forward the law of gas partial pressure, that is, the total pressure of mixed gas is equal to the sum of the partial pressures of each component gas. He also measured the relationship between the density of water and temperature, the thermal expansion coefficient of gas and so on. Unfortunately, Dalton once stubbornly opposed Avon Gardlow's molecular theory preserved for him and passed it as a "joke".

In order to devote his whole life to the cause of science, Dalton never married and engaged in scientific research under harsh conditions. The British government only gave a pension at the appeal of famous European scientists, but Dalton saved the money and gave it to the University of Manchester as a scholarship for students.
