Step 1 Convert known reactant mass to moles In order to relate the amounts H A 2 SO A 4 and NaOH using a mole ratio we first need to know the quantity of H A 2 SO A 4 in moles We can convert the 3 10 grams of H A 2 SO A 4 to moles using the molar mass of H A 2 SO A 4 98 08 g mol You do this by multiplying the moles by the molar mass of the substance This technique is covered in the mole section of the ChemTeam Click this link to go to the proper mole file for review Here is the equation we ll use for the first three examples 2KClO 2KCl 3O Example 1 1 50 mol of KClO decomposes
