39.636 g of an unknown compound X is dissolved in 170.86 mL. What is the molarity of X? Here is some information to determine the identity of X. When 1.00g of X is dissolved in water and allowed to react wtih AgNO3, all the chlorine in X precipitates and 1.95g of AgCl is collected. When 1.00g of X undergoes complete combustion, 0.900 g of CO2 and 0.735 g of H2O were collected. The empirical and molecular formula are identical. Compound X only contains carbon, hydrogen, nitrogen, and chlorine.

A 1.005 g sample of an unknown alkaline-earth metal was allowed to react with a volume of chlorine gas that contains 1.91 × 1022 Cl2 molecules. The resulting metal chloride was analyzed for chlorine by dissolving a 0.436 g sample in water and adding an excess of AgNO3(aq) to give a precipitate of 1.126 g of solid AgCl. What is the percent Cl in the alkaline-earth chloride? What is the identity of the alkaline-earth metal? Write balanced equations for all...
