Question

The experiment calls for preparing one of two salts, either copper(ii) sulfate or potassium aluminum sulfate.  The instructions for the copper(ii) sulfate preparation give a target of between 0.010 and 0.025 moles of the copper(ii) sulfate product.  The instructions also specify to use an excess of sulfuric acid but not more than 5 times the amount required by the balanced equation.  Sulfuric acid will be available as a 6M H2SO4 solution.  What is the volume of 6M H2SO4 required by the balanced equation to react with the CuO to produce 0.025 moles of copper(ii) sulfate.   Report this volume in milliliters to two significant figures.  

The experiment calls for preparing one of two salts, either copper(ii) sulfate or potassium aluminum sulfate. The instructions for the copper(ii) sulfate preparation give a target of between 0.010 and 0.025 moles of the copper(ii) sulfate product. The instructions also specify to use an excess of sulfuric acid but not more than 5 times the amount required by the balanced equation. Sulfuric acid will be available as a 6M H2SO4 solution. What is the volume of 6M H2SO4 required by the balanced equation to react with the CuO to produce 0.025 moles of copper(ii) sulfate. Report this volume in milliliters to two significant figures.

Explanation / Answer

H2SO4 + CuO = CuSO4 + H2O

One to one mole ratio.

.025 moles of copper(II) sulfate = .025 moles of H2SO4.

.025moles/6M = 4.17 mL
