Final answer:
The molarity of the solution is 4.00 M.
Step-by-step explanation:
The osmotic pressure of a solution can be calculated using the formula II = MRT, where II is the osmotic pressure, M is the molarity of the solution, R is the gas constant (0.0821 L.atm/(K·mol)), and T is the temperature in Kelvin. In this case, we are given that the osmotic pressure, π, is 103 atm. To find the molarity of the solution, we can rearrange the formula to solve for M:
M = π / (RT)
Substituting the given values, we get:
M = 103 atm / (0.0821 L.atm/(K·mol) * 298 K) = 4.00 M
