Question

The molar mass of hydrogen (H2) is 2. 02 g/mol. A sample contains 4. 00 mol of H2. What is the mass, in grams, of this sample? 1. 98 grams 2. 02 grams 4. 00 grams 8. 08 grams.

Answer 1

8.08 G/mol

Step-by-step explanation:

This is because a mole just equals 1 amount of something. Example, 1 mol of carbon is about 12 AMU. To convert from Mols to Grams, you need to multiply the substance mass by the amount of mols, this case 2.02g/mol by 4.

Hope this helps!
