    CO + 2H2 = CH3OH
    2mol 1mol

    Equation by Amanda is ok.
    part b is not.

    Convert 45.0 g CH3OH to mols. # mols = grams/molar mass.
    Convert mols CH3OH to mols H2 using the coefficients in the balanced equation.
    Convert mols H2 to grams H2 remembering that grams = mols H2 x molar mass H2.
    Post your work if you get stukc.
