Final answer:
To find the mass ratio of chlorine to calcium, you need to divide the molar masses. Provide more information for Sample 2.
Step-by-step explanation:
The mass ratio of chlorine (Cl) to calcium (Ca) in Sample 1 can be determined by finding the molar mass of chlorine and calcium and then dividing them. Take the atomic mass of chlorine as 35.45 g/mol and the atomic mass of calcium as 40.08 g/mol. The mass ratio is therefore:
(35.45 g/mol)/(40.08 g/mol)
To calculate the mass ratio in Sample 2, you will need to provide more information about the composition of the sample.
