Go from molarity to moles

WebStep 1: Convert known reactant mass to moles In order to relate the amounts \ce {H2SO4} HX 2SOX 4 and \ce {NaOH} NaOH using a mole ratio, we first need to know the quantity of \ce {H2SO4} HX 2SOX 4 in moles. WebAlso, it's this last modification of ppm (the mg/L one) that allows us to go to molarity (which has units of mol/L). The best way to explain this is by doing some examples. Example #1: Convert 78.0 ppm of Ca 2+ ions to mol/L Solution: ... Moles in one liter = mass/molar mass = 0.00289/522 = 5.5 x 10-6 mol Therefore the molarity is 5.5 x 10-6 M.
