- If Epsom salt, MgSO4 x H2O, is heated to 250 C, all the water of hydration is lost. On heating a 1.687-g sample of the hydrate, 0.824 g of MgSO4 remains. How many molecules of water occur per formula unit of MgSO4?arrow_forwardA 4.19-g sample of nitrous oxide (an anesthetic, sometimes called laughing gas) contains 5.73 1022 N2O molecules. How many nitrogen atoms are in this sample? How many nitrogen atoms are in 2.67 g of nitrous oxide?arrow_forwardThe action of bacteria on meat and fish produces a compound called cadaverine. As its name and origin imply, it stinks! (It is also present in bad breath and adds to the odor of urine.) It is 58.77% C, 13.81% H, and 27.40% N. Its molar mass is 102.2 g/mol. Determine the molecular formula of cadaverine.arrow_forward
