WebStep Two: dividing 1.00 mol by 2.00 L gives 0.500 mol/L (or 0.500 M). Comment: remember that sometimes, a book will write out the word "molar," as in 0.500-molar. Example #5:Calculate the molarity of 25.0 grams of KBr dissolved in 750.0 mL. Solution: 1) Convert grams to moles: 25.0 g 0.210 mol 119.9 g/mol 2) Calculate the molarity: 0.210 mol WebJan 3, 2024 · Let's assume that you have 5 g of HCl in a 1.2 liter solution. 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.
