Explanation / Answer

Part A-

Two solutions are of equal concentration, so their osmotic pressure is equal. An isotonic solution refers to two solutions having the same osmotic pressure across a semipermeable membrane.

Substance A has i = 1

Substance B has i = 3

Osmotic pressure () of solutions can be calculated using the following equation- = I MRT

Osmotic pressure of Substance A = iA MRT

Osmotic pressure of Substance B = iB MRT

M and R both are same, so iA TA = iB TB

1TA = 3 TB

Blue line represents a solution A, red line represents a solution B is correct option.

Part B-approximate melting point of the pure liquid solvent = 00C

Part C-

delta T = Kf*m and convert to freezing point.

m = T/Kf

mA = 140C/2.40C/m =M 5.83

mB = 110C/2.40C/m = 4.58M
