Such mixture is called a solution. Moles of solute before dilution = moles of solute after dilution m initial v initial = m final v final example: (0.033395 moles cucl 2) / (0.0515 liters) = 0.648 m. Concentrations and volumes can be in any units, as long as both concentrations are in the same units as each other, and both volumes are in the same units as each other. Web if needed, you can find the molarity of a solution by the usual formula:
