A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile's engine cooling system. If a car's cooling system holds 6.20 gal, what is the boiling point of the solution? For the calculation, assume that at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and 0.998 g/mL respectively. Also, assume that the engine coolant is pure ethylene glycol (HOCH, CH, OH), which is non-ionizing and non-volatile, and that the pressure remains constant at 1.00 atm. The boiling-point elevation constant for water will also be needed. °C %D

Transcribed Image Text:A 50/50 blend of engine coolant and water (by volume) is usually used in an automobile's engine cooling system. If a car's
cooling system holds 6.20 gal, what is the boiling point of the solution?
For the calculation, assume that at normal filling conditions, the densities of engine coolant and water are 1.11 g/mL and
0.998 g/mL respectively. Also, assume that the engine coolant is pure ethylene glycol (HOCH, CH, OH), which is non-ionizing
and non-volatile, and that the pressure remains constant at 1.00 atm. The boiling-point elevation constant for water will also
be needed.

Expert Solution
Step 1
Given:-
Capacity of Car cooling system = 6.20 gal
Density of engine coolant = 1.11g/mL
Density of water = 0.998g/mL
1gallon = 3785.41mL
Molar mass of ethylene glycol = 62.07 g/mol
