A student made copper sulfate using 0.250 moles of copper oxide and 0.500 moles of sulfuric acid. Calculate the maximum mass of copper sulfate which could be produced.
Give your answer to 3 significant figures.
Relative formula mass (Mr) CuSO4 = 159.5 *

39.9g is the maximum mass of copper sulfate which could be produced

Explanation:

1 mole of Copper oxide, CuO contains 1 mole of Cu

In the same way, 1 mole of sulfuric acid, H₂SO₄, contains 1 mole of sulfate ion, SO₄²⁻.

Thus we can understand that there are 0.250moles of Cu and 0.500 moles of SO₄²⁻ to produce CuSO₄.

The maximum moles that could be produced are 0.250 moles (Copper is limiting reactant).

To convert these moles to mass we use the relative formula mass:

0.250 moles CuSO₄ * (159.5g/mol) =
