Answer : The mass of hydrogen gas will be, 5.6 grams.
Explanation : Given,
Mass of C = 34 g
Molar mass of C = 12 g/mole
Molar mass of = 2 g/mole
First we have to calculate the moles of carbon (C).
Now we have to calculate the moles of .
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 1 mole of react to give 1 mole of
So, 2.8 moles of react to give 2.8 moles of
Now we have to calculate the mass of .
Therefore, the mass of hydrogen gas will be, 5.6 grams.
