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 Calculate the work energy, w, gained or lost by the system when a gas expands from 20 L to 35 L A student weighs out 14.9 mg of vanadium. How many moles are in the sample? Determine the number of protons, neutrons, and electrons in the following: 25 X 12 What does "X" represent in the following symbol? 28 X 14 A chemist must prepare 575. mL of 203. μM aqueous magnesium fluoride (MgF2) working solution. She'll do this by pouring out some 549
