4. The vapor pressure of pure water and pure ethanol at 25 \deg C are 24 Torr and 44 Torr, respectively. Suppose you have a water - ethanol mixture and the total vapor pressure is 31.2 Torr. Sucrose, C12H22011, is a non-volatile solute that will not contribute to the total vapor pressure. When 0.03 moles of sucrose is added to the water - ethanol mixture, the vapor pressure drops to 29.8 Torr. How many moles of water are present in the solution?

A common practice in cooing is the addition of salt to boiling water. The boiling point of elevation is described by the equation, which is similar to freezing point depression equation but uses a different constant. imagine that your friend tells you that this is done in order to raise the temperature of the boiling water. If 1.50 kg (1.50L) of water is boiling at 100 degrees celsius how much NaCl (molar mass= 58.44g/mole) would need to be added to the water to increase the boiling point by 1 degree Celsius? Does your friend's explanation make sense?
