When copper (II) sulfate pentahydrate (CuSO4•5H2O) is heated, the water is driven off, leaving behind solid copper (II) sulfate (CuSO4) according to the equation below:

CuSO4•5H2O → CuSO4 + 5H2O

Describe how a chemist should set up his or her stoichiometric calculation to predict the mass of CuSO4 that forms when a specified mass of CuSO4•5H2O is heated.

Which of the following would have less momentum than a 52 kg cheetah running at 10 m/s?
