Molar mass of C = 12 g/mole
Calculate the moles of C as follows:
n = mass/molar mass = 15.5/12 = 1.292 moles.
From the balanced reaction , 1 mole of C will give 1 mole of H2.
Moles of H2 produced = 1.292 moles
Calculate the volume of H2 as follows:
PV = nRT
1*V = 1.292*0.08206*(273 + 27)
V = 31.8 L
Therefore, 2nd option is the correct answer.
Please give good rating.
