Answer:

Subtract the mass of calcium from the total mass. The result is the mass of fluorine in the sample.

Explanation:

Since fluorite #("CaF"_2)"# contains calcium and fluorine, the mass of fluorine can be determined by subtracting the known mass of calcium from the known mass of the fluorite crystal.

#"mass of fluorine"##=##"18.66 g"-"9.590 g"="9.07 g"#
