the fuel methanol(CH3OH) is made by the reaction of carbon monoxide and hydrogen.
a) write the balanced chemical reaction
b)how many grams og hydrogen are needed to produce 45.0 grams of methanol?

CO + 2H2 = CH3OH
45 x 2 = 90 grams
hope i got it right for you

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.
