1. Find Cm and C% of the solution of NH3PO4 where Cn=3, and d=1.2g/ml

2. In 2 Litres of H2O we put 2.24Litres of NH3 (gas) in normal conditions. Find Cm and Cn of the solution.

3. In 500mL H2O we put 0.1 mol Na2O2. Find Cm, Cn, C% of the formed solution.

I've started some of them, and i'm not sure if i'm right or wrong. i'd like some help and if it's possible some explaining.. thanks a lot
