Question #b3655

Answer 1

`0.25 atm`

Explanation:

The formula below will be used as a reference:

Identify the known and unknown variables.

`color(red)("Knowns:"`
`P_1`= 1.00 atm
`V_1`= 0.5 L
`V_2`= 2.0 L

`color(maroon)("Unknowns:"`
`P_2`

Rearrange the equation to solve for the final pressure by dividing both sides by `V_2` to get `P_2` by itself like this:

`P_2=(P_1xxV_1)/V_2`

Plug in your given values to obtain the final pressure:

`P_2=(1.00\atm xx 0.5\ cancel"L")/(2.0\cancel"L")` = `0.25 atm`
