Hulk · Answer 1

Equation:

C + H2O → CO + H2

1mol C produces 1 mol H2

Molar mass Co = 12.01g/mol

mol C in 34g = 34/12.01 = 2.831 mol of C

This will produce 2.831 mol H2

Molar mass H2 = 2016 g/mol

Mass of 2.831 mol H2 = 2.831 * 2.016 = 5.7072g H2 produced

Answer must have 2 significant figures: Mass H2 = 5.7g
