A student performed an experiment to determine the ratio of H2O to CuSO4 in a sample of hydrated copper(II) sulfate by heating it to drive off the water and weighing the solid before and after heating. The formula obtained experimentally was CuSO4∙5.5H2O but the accepted formula is CuSO4∙5H2O. Which error best accounts for the difference in results?<spanclass=′latex−bold′>(A)</span>During heating some of the hydrated copper(II) sulfate was lost<spanclass=′latex−bold′>(B)</span>The hydrated sample was not heated long enough to drive off all the water<spanclass=′latex−bold′>(C)</span>The student weighed out too much sample initially.<spanclass=′latex−bold′>(D)</span>The student used a balance that gave weights that were consistently too high by 0.10 g
