5a) A student strongly heated 3.67 g hydrated calcium chromate in a crucible. After several heatings, the mass of the anhydrous salt was 2.98 g. Based on the student's lab data, calculate the percent of water in the hydrated calcium chromate. b) Use the data given in 5a above to determine the formula of the hydrate. You need to figure out the moles of dry salt and the moles of water and compare the two. You need the specific formula of calcium chromate in order to find the number of moles. Write the formula of the hydrate including ratio to the 0.01 place. It should look like this: salt-x.xx H₂O (fill in the ratio just determined for the x's).
