Question

How many atoms of hydrogen are there in 4.5 moles of hydrogen

Answer 1

We are asked to determine the number of atoms in 4.5 moles of hydrogen. To do that we will Avogadro's number:

`1mol=6.023*10^(23)atoms`

Using the conversion we get:

`4.5mol*(6.023*10^(23)atoms)/(1mol)=27.1*10^(23)atoms`
