    How much copper can be obtained from 100 g of copper sulphate?

    Answer:

    \[CuS{{O}_{2}}\]; Molar mass = 63.5 + 96 = 159.5 g \[\because \]\[159.5\,g\,CuS{{O}_{4}}\] contains 63.5 g copper \[\therefore \]\[100g\,CuS{{O}_{4}}\] will contain \[\frac{63.5}{159.5}\times 100g\] copper = 39.81 g
