Practice Question #6 – Gram to Gram Mole Ratio Stoichiometry
1. Copper I iodide, CuI, is not stable enough to last long in storage, so it is generally made just prior to use. In can be prepared from copper sulphate and hydriodic acid by the following reaction. SHOW WORK!
2 CuSO4 + 4 HI -------> 2 CuI + 2 H2SO4 + I2
If 34.56 grams of HI is used, calculate the number of grams of each of the products that are produced.
