Calculate the number of atoms in 10g of hydrogen atoms.?
- 2 months ago
Hydrogen atoms have a molar mass of 1.008 g/mol, so there are 10 g / 1.008 g/mol = 9.92 moles of hydrogen atoms in a 10 g sample.
Then, multiply by Avogadro's number: 9.92 * 6.022 * 10^23 = 5.97 * 10^24 atoms
This is a very large number, which is why we generally speak in terms of moles instead of particles when talking about quantities of substances.
