And thus we calculate the equivalent quantities of "silver ion" and "chromate ion". "Moles of silver nitrate"=0.150*Lxx0.500*mol*L^-1=0.0750*mol. "Moles of potassium chromate"=0.100*Lxx0.400*mol*L^-1=0.0400*mol. Clearly, silver nitrate is the limiting reagent, as there is a stoichiometric excess of chromate ion.

Molarity Calculator [with Molar Formula]
Convert the expressions above to obtain a molarity formula. As mass / volume = molarity * molar mass, then mass / (volume * molar mass) = molarity. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass.
