Question

Helpppp

In an experiment, 2.3754 g of copper (II) sulfate pentahydrate is heated to drive off all the water of crystallization. Write a balanced equation. Determine the mass of anhydrous salt that remains. Show your calculations. Possible unknowns for this experiment include CuSO45 H2O, MgSO47H2O, and KA1(SO4)212 H2O. Calculate the percent water by weight in each of these hydrates, show all calculations? NOTE: You will use this at the end of your experiment to identify your unknown hydrate. A hydrate of sodium phosphate, Na3PO4, contains 49.7% water by weight. How many grams of water and how many grams of anhydrous Na3PO4 are in 1000. grams of this sample? In this same 1000.-gram sample, how many moles of water and how many moles of anhydrous Na3PO4, are present? What is the formula of the hydrate?
