Dilutions Worksheet Answers. Here are some ways to think about making dilutions of solutions that we commonly use in biology tiet dilute a 90% solution to make 90 ml of a 75% solution. Web answers m 1 v 1 = m 2 v 2 (1.71 m) (25.0 ml) = m 2 (65.0 ml) m 2 = 0.658 m m = mol/l = (25.0/40.0) / (0.325) = 1.92 mol/l g = (m) (l) (fw) = (0.400) ( (0.225) (119) = 10.7 g.
