write the reaction equation
WO3 + 3H2 = 3H2O + W
find the molar mass of tungsten
M (W) = 184 kg
mass of tungsten
m (W) = 184 kg
molar mass of hydrogen
M (H2) = 1 kg / kmol
mass of hydrogen
m (H2) = 1 kg / kmol * 3 kmol = 3 kg
We get the proportion:
X kg (H2) -1 kg (W)
3 kg (H2) – 184 kg (W)
X = 0.016
