Excess ( NH4)2SO4 was added to a 55.0 mL solution containing BaCl2 (MW = 208.23 g/mol). The resulting BaSO 4 (MW = 233.43 g/mol) precipitate had a mass of 0.3168 g after it was filtered and dried.
What is the molarity of BaCl2 in the solution?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
