## Question:

A mixture of {eq}CuSO_4 \cdot 5H_2O {/eq} and {eq}MgSO_4 \cdot 7H_2O {/eq} is heated until all water is lost. If 5.020 g of the mixture gives 2.988 g of the anhydrous salts, what is the percent by mass of {eq}CuSO_4 \cdot 5H_2O {/eq} in the mixture?

## Hydrated Salt:

Salts that have water molecules within their crystals are known as hydrated salts. {eq}MgSO_4\cdot 7H_2O \space and \space CuSO_4\cdot 5H_2O {/eq} are examples of hydrated salts. When these salts are heated, they lose water and become anhydrous salts ({eq}MgSO_4 \space and \space CuSO_4 {/eq}).
