Northern cod produce proteins that protect their cells from damage caused by subzero temperatures. Measurements of the osmotic pressure for two antifreeze proteins at 18C yielded the data listed below. Use this information to calculate the molar mass for each of the proteins. Assume these proteins are nonelectrolytes and use the value i = 1.

Part 1: If a 55.5 mg sample of protein A in 1.5 mL of water has an osmotic pressure of 0.281 atm, what is the molar mass of protein A in g/mol?

Part 2: If a 50.3 mg sample of protein B in 1.75 mL of water has an osmotic pressure of 0.218 atm, what is the molar mass of protein B in g/mol?
