Explanation:

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant  R .  Suppose the osmotic pressure of a certain solution is measured to be  22 atm  at an absolute temperature of  353 K.  Write an equation that will let you calculate the molarity  c  of this solution. Your equation should contain only symbols. Be sure you define each symbol other than  R.

Step 1: Given data and definition of the symbols

Step 2: Write an equation that will let you calculate the molarity of this solution, in terms of symbols

The osmotic pressure is a colligative property that can be calculated using the following expression.

π = c × R × T

We can rearrange this expression to calculate the molarity of the solution.

c = π / R × T
