Suppose the osmotic pressure of a certain solution is measured to be 22. atm at an absolute temperature of 302. K. Write an equation that willlet you calculate the molarity c of this solution. Your equation should contain only symbols. Be sure you define each symbol other than R | Your equation: 2 Definitions of your symbols: 1-22. atm =302, K

Explanation / Answer

since osmotic pressure,
p = c*R*T
c = p/(R*T) <— this is equation
p = 22 atm
T = 302 K
c = p/(R*T)
= 22/(0.0821*302)
= 0.89 M

Answer: 0.89 M
