The Osmotic Pressure of a Solution is Determined By

Question

The osmotic pressure of a solution is determined by
A)the number of particles dissolved in that solution.
B)the size of particles dissolved in that solution.
C)the weight of particles dissolved in that solution.
D)all of the choices are correct.
E)none of the choices is correct.

Accepted Answer

The osmotic pressure of a solution is determined by the number of particles dissolved in that solution. This is because osmotic pressure is directly proportional to the concentration of particles in a solution, according to the equation pi = MRT where π is osmotic pressure, M is the molarity of the solution, R is the gas constant, and T is the temperature in Kelvin. Therefore, choice A is the correct answer.
