Question 1

Calculate the boiling point of a solution of 500.0 g of ethylene glycol (C2H6O2) dissolved in 500.0 g of water. Kf = 1.86 °C m-1 and Kb = 0.512 °C m-1. Use 100 °C as the boiling point of water.
◦ 8.3 °C
◦ 92 °C
◦ 70 °C
◦ 108 °C
◦ 130 °C

Question 2

The boiling point elevation of an aqueous sucrose solution is found to be 0.39 °C. What mass of sucrose (molar mass = 342.30 g mol-1) would be needed to dissolve in 500.0 g of water? Kb (water) = 0.512 °C m-1.
◦ 261 g sucrose
◦ 223 g sucrose
◦ 762 g sucrose
◦ 130. g sucrose
◦ 528 g sucrose
