The freezing point depression can be explained in terms of vapor pressure adding solvent will decrease molecules
Answer:
50 mL
Explanation:
We can solve this problem by using Boyle's Law, which states that:
"For a fixed mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume"
Mathematically:

where
p is the pressure of the gas
V is the volume of the gas
The equation can be rewritten as

where in this problem:
is the initial pressure of the gas in the coke
is the initial volume
is the final pressure
Solving for V2, we find the final volume:
