Answer : The mass of this sample is, 8.08 grams

Explanation : Given,

Molar mass of
H_2 = 2.02 g/mol

Moles of
H_2 = 4.00 mol

Formula used :


\text{Mass of }H_2=\text{Moles of }H_2* \text{Molar mass of }H_2

Now put all the given values in this formula, we get the mass of this sample.


\text{Mass of }H_2=4.00mol* 2.02g/mol


\text{Mass of }H_2=8.08g

Therefore, the mass of this sample is, 8.08 grams.
