Answer:
Hydrogen has a molar mass of 1.008 grams per mole so 1.10g is slightly over a mole
Explanation:
Chromium has a molar mass of 51.996g. 14.7 is much less than that. Since the mole is basically a measure of the number of atoms, once you have moles you can go anywhere. You can compare them directly now. Hydrogen would have more atoms
The math would be :
1.10g *1mol/1.008g*(6.022x10^23atoms)/1mole= 6.56x10^23 atoms of H
14.7g*1mole/51.996g*(6.022x10^23atoms)/mole= 1.70x10^23 atoms Cr
