What mass of anhydrous copper 2 sulfate can be obtained by heating 125g of cuper 2 sulfate pentahydrate?

To find the mass of anhydrous copper(II) sulfate obtained:

1. Calculate the molar mass of each compound: CuSO4·5H2O (pentahydrate) and CuSO4 (anhydrous).
2. Use the molar ratio between CuSO4 and CuSO4·5H2O to find the amount of anhydrous CuSO4.
3. Convert the amount to mass using the molar mass of CuSO4.

The mass of anhydrous CuSO4 will be less than the initial 125g due to the loss of water upon heating.
