At 36°c, what is the osmotic pressure of a 0.82% nacl by weight aqueous solution? assume the density of the solution is 1.0 g/ml. (r = 0.0821 l · atm/(k · mol)) a. 7.1 atm b. 0.35 atm c. 0.82 atm d. 4.1 × 102 atm e. 3.5 atm

e. 3.5 atm

Explanation:

= osmotic pressure  = ?

C= concentration in Molarity

R= solution constant  = 0.0821 Latm/Kmol

T= temperature =

For the given solution: 0.82 grams of is dissolved in 100 g of solution.

Putting in the values we get:

The osmotic pressure of a 0.82% NaCl by weight aqueous solution is 3.5 atm
