Which has more S by mass: 1 gram of MgS or 1 gram of Na2S? Compared to the mass of sulfur in a 1.00 g sample of MgS, the mass of sulfur in a 1.00 g sample of Na2S is You Might Also Like AP Chemistry Unit 1 Sections 1.5 and 1.6 A sample of pure calcium fluoride with a mass of 15.0 g contains 7.70 g of calcium. How much calcium is contained in 45.0 g of calcium fluroride? Determine the number of protons, neutrons, and electrons in the following: 25 X 12 How many electrons are in the ion, P3-? A chemist must prepare 575. mL of 203. μM aqueous magnesium fluoride (MgF2) working solution. She'll do this by pouring out some 549
