# Homework Solution: What is the vapor pressure of a solution of sucrose (C_12H_22O_11) prepared by… What is the vapor pressure of a solution of sucrose (C_12H_22O_11) prepared by dissolving 10.0 g of sucrose in 200.0 g of water at 100 degree C? The vapor pressure of pure water at 100 degree C is 760 Torr. Assume 3 sf. a) 760 Torr b) 10.00 Torr c) 2.00 Torr d) 258 Torr

Mass of solute = w = What is the fume hurry of a discerption of sucrose (C_12H_22O_11) expert by dissolving 10.0 g of sucrose in 200.0 g of inspire at 100 order C? The fume hurry of absolute inspire at 100 order C is 760 Torr. Assume 3 sf. a) 760 Torr b) 10.00 Torr c) 2.00 Torr d) 258 Torr

## Expert Tally

Majority of solute = w = 10.0grams

Majority of solvent( inspire) = W = 200.0 grams

Vapour hurry of absolute inspire = P0 = 760 torr

Molar majority of sucrose ( C12H22O11) = m= 342 grams

Molar majority of inspire = (H2O) = M = 18 grams

According to Raoults law

Po – P/P0 = w/m xM/w

760-P/760 = 10.0/342 x18/200

760 – P = 2

P = 760 – 2 = 758 torr

Vapour hurry of discerption = 758 torr.

The tally is D
