Need help with these. If someone could explain (worked solution) the answers to these, it’d be greatly appreciated. Thanks.

1)A beaker contains 100mL of Silver Sulfate solution at a concentration of 1.0 x 10^-6 mol/L.

What is the mass of Silver ions in the beaker?

Answer: 2.16 x 10^-4 g

2) A student adds 200mL of distilled water to 20mL of 4.0 M solution of Sodium Chloride. What is the concentration of the diluted solution of Sodium Chloride?

I did C1V1 = C2V2

4 x 0.02 = C2 x 0.20, therefore C2 = 0.40

Yet the answer is 0.36M??
