Splet11. jul. 2016 · Next, the equation has to be rearranged to solve for the moles of solute: Moles of solute = Molarity × Liters of solution. Now, multiply 0.360 M by 0.05: 0.360 mol 1 L ×0.05 L = 0.018 mol. To obtain the mass of solute, we will need to the molar mass of NaCl, which is 58.44 g/mol: Finally, multiply the number of moles by 58.44 g/mol. Splet02. okt. 2024 · Liters of solution = mL of solution x (1 L/1000 mL) Liters of solution = 750 mL x (1 L/1000 mL) Liters of solution = 0.75 L. This is enough to calculate the molarity. …
