The mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
According to this question, a 10.4 g sample of CaSO4 is found to contain 3.06 g of Ca and 4.89 g of O.
This means that the mass of sulfur in the 10.4g of CaSO4 is 10.4g - (3.06g + 4.89g) = 10.4g - 7.95g = 2.45g
Next, we calculate the percent ratio of each element in the compound; CaSO4.
According to this question, a sample of CaSO4 with a mass of 65.8 g is given. The mass of each element in this compound is as follows:
Therefore, the mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
