Answer to Question #238787 in General Chemistry for Ins

Question

an excess of copper(II) oxide is reacted with 1.0 mol dm3 sulphuric acid. Calculate the volume of sulphuric acid needed to prepare 20.0 g of copper(II) sulphate.

Answer 1

CuO + H₂SO₄ ==> CuSO4 + H2O.....

moles of H₂SO₄ = moles of CuSO₄= (20/159.6) = 0.12531....

Volume of acid= ( 0.12531 × 1000)/1.0

= 125.3 mL
