(a)
Interpretation: The density of the antifreeze mixture that freezes at
Concept Introduction: The temperature at which a liquid transforms into a solid when cooled is known as the freezing point. The mass of a substance per unit of volume is known as its density.

(c)
Answer to Problem 75A
The freezing point of a mixture that is
Explanation of Solution
With the help of a graph, the required data are interpreted.
On the graph, A represents 20% (EG) by mass and B represents 40% (EG) by mass.
The mixture that has a mass of 30% is in between A and B freezing points in the graph.
So, the freezing point is
