1.0 g of a protein is dissolved in 100 ml of distilled water. The resulting solution has an osmotic pressure of 0.001 atm at room temperature. What is the molecular weight of the protein?

The molar mass of the protein is 244678.2 g/mol

Explanation:

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

where,

= osmotic pressure of the solution = 0.001 atm

i = Van't hoff factor = 1 (for non-electrolytes)

c = molarity of solute = ?

R = Gas constant =

T = temperature of the solution =

Putting values in above equation, we get:

To calculate the molecular mass of solute, we use the equation used to calculate the molarity of solution:

We are given:

Molarity of solution =

Given mass of protein = 1.0 grams

Volume of solution = 5.00 mL  

Putting values in above equation, we get:  

Hence, the molar mass of the protein is 244678.2 g/mol

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
