Suppose you begin with 1.50~g of the hydrate copper(ii)sulfate · x-hydrate (cuso4· x h2o), where x is an integer. after dehydration you find that you are left with 0.96~g of the an-hydrate cuso4. what is the unknown integer x? round your answer to the nearest integer, enter only an integer. suppose you begin with of the hydrate kal(so4)2 · 12h2o. after dehydration you find that you are left with 3.0~g of the an-hydrate kal(so4)2. how many grams did you start with? write the value to the correct number of significance figures.
