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

1.88 L

Step-by-step 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=(p_1 V_1)/(p_2)=((1.21)(1.04))/(0.671)=1.88 L`
