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 6.50 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 (HOCH₂CH₂OH), 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. Tb. = 'C
