The soda water didn't freeze because of the depression in freezing point as compared to the water.
<h3>What is Freezing Point Depression ?</h3>
When a solute is added to a pure solvent , then the value of freezing point is reduced.
The decrease in the freezing point is directly proportional to the molality of the solute.
It is given in the question that
A student put a bottle of water and a can of sugared soda in the freezer to chill them quickly.
when she took them out, the bottle of water was frozen but the can of soda was not.
It is because water is the pure solvent , so freezing point is fixed but the soda water has sugar and Carbon Di oxide along with the solvent water , the presence of the sugar and Carbon -di-oxide decreases the freezing point of the soda water and so it doesn't freezes.

Answer: -
71
Explanation: -
From the diagram, we see that volume goes from 70 to 75 in 5 markings.
Each marking is for 1.
It is the most accuracy possible as there is no smaller marking.
Significant figures expresses the required amount of accuracy.
Thus the volume indicated from the diagram is 71 .
