Aprotein subunit from an enzyme is part of a research study and needs to be characterized. a total of 0.155 g of this subunit was dissolved in enough water to produce 2.00 ml of solution. at 28 ∘c the osmotic pressure produced by the solution was 0.138 atm. what is the molar mass of the protein?

Answer : The molar mass of protein is,

Explanation :

Formula used :

where,

= osmotic pressure  = 0.138 atm

C = concentration

R = solution constant  = 0.0821 L.atm/mol.K

T = temperature  =

w = mass of protein subunit = 0.155 g

M = molar mass of protein subunit = ?

V = volume of solution  = 2.00 mL

Now put all the given values in the above formula, we get:

Therefore, the molar mass of protein is,
