A solution of an 1.24 g of an unknown protein dissolved in enough water to make 0.020 L of solution has an osmotic pressure of 224 torr atm at 25 °C. Based on these data, what is the molar mass of the protein?
Expert Solution
Step 1
Given,
Weight of the protein =1.24g
Volume of the solution = 0.02L
Osmotic pressure = 224 torr = 0.295 atm
Temperature = 25℃ = 298 K
Molar mass of protein = ?
