1. .9295 g of a hydrate was of cobalt chloride, CoCl2 * x H2O is heated until it reaches a constant weight of .5976g. Calculate the value of x.
2.If the sample of CoCl2 * H2O in problem 1 had not been heated to complete dehydration, would the calculated molar ratio of H2O to CoCl2 remain unchanged, or wil it be smaller or greater than the value you calculated in problem 1? Explain your answer.
3. 2.3824 g of anhydrous CuSO4 were exposed to moist air for an extended period of time. Assuming that the hydrated salt formed is saturated with water to a limit consistent with the stoichiometric formula CuSO4 * 5H2O, calculate the weight of the hydrated formula sample.
Thank you in advance for any help you can provide..Please show your work.
