Answer:
13924g/mol is the molar mass of the protein
Explanation:
<em>What is the molar mass of the protein.</em>
<em />
The osmotic pressure of a solution, π, is defined as:
π = c*R*T
<em>Where π is osmotic pressure = 2.054torr* (1atm/760torr) = 2.70x10⁻³atm</em>
<em>c is molar concentration of the protein,</em>
<em>R is gas constant = 0.082atmL/molK</em>
<em>And T is absolute temperature = 298K</em>
Solving the molar concentration:
c = π / RT
c = <em>2.70x10⁻³atm / 0.082atmL/molK*298K</em>
<em>c = 1.106x10⁻⁴ moles protein / L</em>
The moles of protein in 150mL = 0.150L:
0150L * (1.106x10⁻⁴ moles protein / L) = 1.659x10⁻⁵ moles protein
The molar mass is the ratio of mass and moles:
0.231g / 1.659x10⁻⁵ moles protein =
<h3>13924g/mol is the molar mass of the protein</h3>
