Question

a gas has a pressure of 1.21 atm and a volume of 1.04 L. What is the new volume at 0.671 atm

Answer 1

Answer:

1.88 L

Explanation:

We can solve this problem by using Boyle's law, which states that:

"For a fixed mass of an ideal gas at constant temperature, the pressure of the gas is inversely proportional to its volume"

In formula:

$pV=const.$

where

p is the gas pressure

V is the gas volume

We can write the formula as

$p_1 V_1=p_2 V_2$

For the gas in this problem we have:

$p_1=1.21 atm$ is the initial pressure

$V_1=1.04 L$ is the initial volume

$p_2=0.671 atm$ is the final pressure

Therefore, the new volume is

$V_2=\frac{p_1 V_1}{p_2}=\frac{(1.21)(1.04)}{0.671}=1.88 L$
