Question

Is the osmotic pressure of a 0.10 M solution of NaCl greater than, less than, or equal to that of a 0.10 M solution of KBr?a. equal tob. greater thanc. less thand. insufficient information

Answer 1

a. equal to

Step-by-step explanation:

The osmotic pressure is calculated by the formula:

π = i * M * R * T

Where π is the osmotic pressure, M is the concentration, R is a constant, T is temperature and i is the van't Hoff's factor (the number of ions a compound forms when dissolved in water, for both NaCl and KBr is 2).

Because R is always the same, and Temperature and Concentration are equal between the two solutions, the osmotic pressure of both solutions are also equal.
