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:
1.204 × 10²³
Explanation:
The number of atoms in a mole is always 6.022 × 10²³, known as Avogadro's number or Avogadro's constant.
To convert moles to atoms, multiply the molar amount by Avogadro's number.
(6.022 × 10²³) × 0.2
= 1.204 × 10²³
