The Mole Webquest

How many grams in 1.2 moles of H2O? How many grams in 0.87 moles of H2O2? How many grams in 0.43 moles of C6H12O6? Can I apply this somehow to volume? Well at standard temperature and pressure (STP) a mole of a gas will occupy 22.4 liters. So If we keep our units straight we should be able calculate a given volume of gas from moles. ................
