4) George and Max are preparing soup. Max puts 1500 g of water into a cooking pot and adds 68 g of the NaCI (MW=58.5 g/mol). a) What will be the boiling point of the solution? (Kb water is 0.51 °C/m) b) How much NaC1 (in gram) should Sam add to the pure water, if they want the freezing point of the soup to be lowered by 5°C, so that it won't freeze at 0 °C? (Kf of water is 1.86 °C/m)
