Describe how to convert between mass and the number of moles of a substance.

Ammonium carbamate (NH2COONH4) is a salt of carbamic acid that is found in the blood and urine of mammals. At 250.°C, Kc = 1.58 * 10-8 for the following equilibrium: NH2COONH4 (s) ⇌ 2 NH3 (g) + CO2 (g) If 11.51 g of NH2COONH4 is put into a 0.

Consider a 1.24 g mixture of magnesium nitrate and magnesium chloride. After dissolving this mixture in water, 0.500 M silver nitrate is added dropwise until precipitate formation is complete. The mass of the white precipitate formed is 0.419 g.
