C 185 If 35.8 mg of the compound is dissolved in enough water to make 175 mL of solution at 25C, what is the osmotic pressure of the resulting solution? Equilibrium constant Kp is equal to the partial pressure of products divided by partial pressure of reactants and the partial pressure are raised with some power which is equal to the coefficient of the substance in balanced equation.
