Questions:

1. What is the value of the temperature to be used to solve for the osmotic pressure of the solution?

2. What is the osmotic pressure of solution?

3. At the same temperature, what will be the molar concentration of glycerol considering the computed osmotic pressure of the solution and the normal osmotic pressure inside a yeast cell of 7.3 atmospheres?

Yeasts are able to produce high internal concentrations of glycerol to
counteract the osmotic pressure of the surrounding media. Suppose
that a sample of yeast cells were placed in a 4% sodium chloride
solution by weight.
Density of solution at 25 °C = 1.02 g/mL
MW of solute = 58.44 g/mol
i of glycerol = 1
R = 0.08205 L-atm/mol·K
