Solution

The correct option is A 12
Gram atomic mass of carbon = 12 g

Gram atomic mass of hydrogen = 1 g

The chemical reaction for formation of methane is as follows:

$C (s) + 2 H_{2} (g) \to C H_{4} (g) 12 g 4 g 16 g$

Thus, 12 g of carbon react with 4 g of hydrogen to produce 16 g of methane.

Hence, mass of hydrogen required to react with 36 g of carbon = $\frac{4}{12} \times 36$ = 12 g
