I guess we should get something started here. Let's make it easy.

1. How much water must be added to a 50 mL 1.5 M NaCl solution to create a 0.4 M solution?

2. What is the molality of a solution if 40 grams of NaCl is added to 2 liters of water?

Didn't use sig figs:
1. 187.5 mL needed, so 137.5 mL should be added
2. 0.342 m
