Convert 350.0 mL at 0.97 atm to its new volume at standard pressure (1 atm).

339.5 mL

Explanation:

Assuming the temperature of the gas remains constant, we can solve this problem by using Boyle's Law, which states that:

"When a constant mass of an ideal gas is 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

This equation can be rewritten as

where in this problem:

is the initial pressure of the gas

is the initial volume of the gas

is the final pressure

Solving for V2, we find the final volume:
