A biochemist is thrilled with her discovery of a new enzyme. In order to characterize this new enzyme, she uses osmotic pressure. A solution containing 0.190 g. of this enzyme in 187. mL of solution has an osmotic pressure at 298 K. of 1.18 torr. What is the molar mass of this new enzyme? Error duplicate problem...not on test...remember to convert torr to atm and mL to L. Be able to solve for MM from fp depression or bp elevation data
