Question
A 35.0g sample of ethylene glycol is dissolved in 500.0g of water. The vapor pressure of water at 32C is equal to 35.7mm Hg. What is the vapor pressure of the water-ethylene glycol solution at 32C?
Answers
mol ethylene glycol = 35.00/molar mass = ?
mol H2O = grams/molar mass
Xethylene glycol = n eth/total mols
psoln = Xethyl gly*P<sup>o</sup><sub>H2O
mol H2O = grams/molar mass
Xethylene glycol = n eth/total mols
psoln = Xethyl gly*P<sup>o</sup><sub>H2O
