8. A 200 mL dilute solution of anhydrous CuSO4 with molarity of 0.28 M was made by adding 56 mL of a stock solution, then filling to the 200 mL mark with water. What's the concentration of the original stock solution? M₁ V₁ = M₂ V₂

Calcium sulfate  (MM= 136.1406) dissolves in cold water to the extent of 0.241 g per 100. mL. What is the concentration  (mol/L) of calcium ions in this solution? Hint: CaSO4-> Ca+2+ SO4-2

A student determined the concentration of NaOCI in a commercial bleach sample using the same technique described in section "F" of the Halogens and Their Compounds lab. The student required 18 drops of 0.01M Na,S203 to reach the end point. What is the concentration (reported in molarity) of NaOCI in the bleach sample?
