Suppose you want to cook pasta in boiling, salty water. What is effect of salt (NaCl) addition to water on the boiling point temperature of the resulting solution? Justify your answer by calculating the changes in the vapor pressure of pure water vs. salty water at 100 °C. Assume you add 100.0 g of salt to 1.00 liter (1000 mL) of water. Vapor pressure of pure water is 760 mmHg. Assume density of water as 1 g/mL.
Arrange the following molecules in the expected order of increasing boiling points: carbon tetrabromide, CBr4; butane, CH3CH2CH2CH3; fluorine, F2
