Determine the new concentration of the resulting solution. A solution is made by dissolving 55.8-g of copper (II) nitrate in enough water to make 450. mL of solution. Calculate the molarity of this solution. Determine the new molarity if 300. mL of this solution is poured into a beaker and 1.50L of pure water is added to this beaker.
Molarity - Quia
For a solution with a known molarity, the moles of the solute in the solution are easily calculated. For example, 250 mL of a 1.00M KCl solution has 0.250 moles of the solute. Once the number of moles present are calculated, the mass of KCl required to prepare the solution can be calculated.
