Work Step by Step
Use molar mass to convert mass into moles. The volume of one mole of gas at STP is 22.4 L. Use this as a conversion factor as well.
Use Avogadro's number and the molar mass of aspirin to make the necessary conversions.
Use Avogadro's number to determine the number of molecules. Then count the number of atoms in a single molecule of ammonium nitrate by inspection and use this as a conversion factor.
