The balanced equation for considered reaction can be written as follows

"C(s) + 2H_{2}(g) \\rarr CH_{4}(g)"


"\\frac{V(H_{2})}{N(H_{2}) \\cdot V_m} = \\frac{V(CH_{4})}{N(CH_{4}) \\cdot V_m}"

V - volume

N - coefficient in chemical equation

Vm - molar volume

"V(H_{2}) = \\frac{V(CH_{4}) \\cdot N(H_{2})}{N(CH_{4})}"

"V(H_{2}) = \\frac{145 \\cdot 2}{1}=290 \\; L"


Answer: 290 liters.
