Homework Help: Chemistry..

Posted by Saira on Friday, May 29, 2009 at 12:43pm.

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 mL of solution. At 28C the osmotic pressure produced by the solution was 0.138 atm. What is the molar mass of the protein?


This is what i used:

PV= nRT
PV= (m/M)RT
Molar mass= (0.180g)(0.0821)(30lk)/(0.000276kg)(0.138)
= 16115.942

Which is wrong can someone please help me.
