Transcribed Image Text:Answer the guide questions below by using the given data in this image.
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
