The osmotic pressure of human blood is 7.6 atm at 37°C.

Question

The osmotic pressure of human blood is 7.6 atm at 37°C. What mass (in g) of sucrose, (C12H22O11, 342.3 g/mol), is required to make 1.00 L of aqueous solution if the solution must have the same osmotic pressure as blood at body temperature, 37°C?

Answer 1

∏ = iMRT

7.6 atm = (1)(M)0.0821)(310)

M = 7.6/(0.0821)(310)

mass = M x 342.3 = grams sucrose per liter
