You carry out the reaction as described in the lab, using 6.00 g of copper, 38.8 mL of 3.0 M H2SO4, and 16.6 mL of 16 M HNO3. What is the limiting reagent in this reaction? What is the theoretical yield of CuSO4·5H2O in grams? Cu(s) + 2 HNO3(aq) + H2SO4(aq) + 3 H2O(l) → CuSO4∙5H2O(s) + 2 NO2(g)

Please show work
Percent Copper in CuSo 5 H2O Background The Law of Definite Composition states that the percent by mass of each element in a compound is constant. For example, sodium chloride is 39.3% by mass sodium and 60.7% by mass chlorine. Any sample of sodium chloride no matter what its size or origin will have that composition. In this experiment you will practice determining the percent silver in silver nitrate as a dry lab. This is called a...
