A protein subunit from an enzyme is part of a research study and needs to be characterized. A total of 0.180 g of this subunit was dissolved in enough water to produce 2.00 \rm mL of solution. At 28 ^\circ \rm C the osmotic pressure produced by the solution was 0.138 \rm atm. What is the molar mass of the protein?
