Methanol (CH3OH) is used in the production of many chemicals. Methanol is made by reacting carbon monoxide and hydrogen at high temperature and pressure.
CO(g) + 2 H2(g) CH3OH(g)
(a) How many moles of each reactant are needed to produce 4.83 102 g CH3OH?
(b) Calculate the number of grams of each reactant needed to produce 3.37 mol CH3OH.
(c) How many grams of hydrogen are necessary to react with 2.45 mol CO?
How many mols CH3OH do you have? That is mols = grams/molar mass.
Use the coefficients to convert mols CH3OH to mols of anything in the equation.
