I'm not sure about the process on how to calculate the molarity, please help me out! What is the molarity of a solution containing 83 g of NaCl in 200. mL of solution?

Nitrogen dioxide decomposes according to the reaction 2 no2(g) ⇌ 2 no(g) + o2(g) where kp = 4.48 × 10−13 at a certain temperature. if 0.70 atm of no2 is added to a container and allowed to come to equilibrium, what are the equilibrium partial pressures of no(g) and o2(g)

What is the vapor pressure of a solution with a benzene to octane?

Which process describes vaporization that takes place below the surface of a liquid? condensation melting boiling evaporation
