Ответ:
158.0 mL
Explanation:
We can solve this problem by using Boyle's law, which states that:
"For a fixed mass of a 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 its volume
The equation can be rewritten as
where in this problem:
Solving for V2, we find the final volume:
