Question
Determine the mol H2O/mol CaSO4 if you have the following data to two decimal places
(MM H2O =18.02 g/mol; MM CaSO4 = 136.14 g/mol)
mass of sample | 1.07 |
mass of water in sample | 0.22 |
mass of CaSO4 in sample | 0.75 |
Expert Solution
Step 1
In this problem, we were asked to determine the mol H2O/mol CaSO4 ratio given the masses of water and CaSO4 in a sample and their molecular weights. The mol H2O/mol CaSO4 ratio provides information about the stoichiometry of a chemical reaction or a chemical compound. The calculation involves first determining the number of moles of H2O and CaSO4 in the sample using their molecular weights and the given masses, and then calculating the ratio of these moles to obtain the desired ratio.
