Step-by-step explanation:

Hello! The answers you are looking for are stated above, taken directly from the periodic table, with avogadro's rule applied. Thank you, hope this comes to your help!

Answer 2

=2.016 g/ mol

Step-by-step explanation:

1 atom of hydrogen has an atomic mass of 1.008 g. Hydrogen molecule is made up of two atoms of hydrogen therefore, it has a mass of:

1.008 g × 2=2.016 g

1 mole of hydrogen gas contains the Avogadro's number of molecules.

Thus M =(L × 2.016g) =2.016g/mol
