Question

find the mass of 1 mole of hydrogen atoms

Answer 1

This means that 1 MOLE of hydrogen atoms will weigh 1.008 grams. That said, to find the mass of one ATOM, we need to convert from moles to atoms as follows:

1.008 grams/mole Hydrogen * (1 mole/6.022x1023 atoms) = 1.67 x 10-24grams.
16.00 grams/mole Oxygen * (1 mole/6.022x1023 atoms) = 2.66 x 10-23grams.

Answer 2

6.022*1023=1mole of hydrogen atoms
