1. Write and balance the equation. You have that.
2. mols CH4 = grams/molar mass = ?
3. Using the coefficients in the balanced equation, convert mols methane to mols H2. For every mols CH4 you will need 2 mols H2.
4. Now convert mols H2 to grams H2.
grams H2 = mols H2 x molar mass H2 = ?
This 4 step procedure works for all stoichiometry problems. With a slight modification it works on limiting regent problems also.
