A hydrate of potassium carbonate has the formula K2CO3⋅xH2O. A 10.00g sample of the hydrated salt is heated and forms 7.93g of anhydrous salt.
(1) Calculate the number of moles of water in the hydrated sample.
(2) Calculate the number of moles of anhydrous salt that form.
(3) Determine the formula of the hydrate.
(4) How could you determine when all the hydrated salt has been converted into anhydrous form?
