Two samples of calcium fluoride are decomposed into their constituent elements. The first sample produced 0.154 g of calcium and 0.146 g of fluorine. If the second sample produced 294 mg of fluorine, how many grams of calcium were formed?

Question

Quizplus · Accepted Answer

The ratio of calcium to fluorine in the first sample is 0.154 g Ca / 0.146 g F. Using this ratio, for 294 mg (0.294 g) of fluorine in the second sample, the amount of calcium is (0.154/0.146) * 0.294 g = 0.309 g.
