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.

The 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. By dividing first the mass of CuSO4•5H2O by its molar mass then multiply it by the stoichiometric ratio of CuSO4/ CuSO4•5H2O and then multiply the molar mass of CuSO4.

Convert mass of CuSO4•5H2O to moles using molar mass of CuSO4•5H2O.

Convert moles of CuSO4•5H2O to moles of CuSO4 using a mole ratio.

Convert moles of CuSO4 to mass of CuSO4 using molar mass of CuSO4.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

c) should be the answer.
