##### How to find the volumes needed to mix two solutions from molarity and density?
« on: July 01, 2018, 12:58:06 AM »
How can i find the volume proportions of a final solution of NaOH of 10L and 0.55 [M] made by mixing a determined volume of two solutions (sol1 and sol2, both of NaOH(ac)) if i only know the molarity of sol1 (0.5 M), the density of sol1 (20 g/L) and the molarity of sol2 (0.65 M)??

Please help, im not asking you to do it (unless you got the time) but maybe just guide me here?

Do you know the  cross rule (Mischungskreuz)? But its also possible to develop mathematic equations.
