Question #423de

Answer 1

`58°C`

Explanation:

We are given the following

`P` = 7.25 atm
`V` = 1.52 L
`n` (mol) = .406
`R` = .0821 `(L * atm)/(mol * K)`
`T` = unknown
we are asked to find temperature. Using the ideal gas law `PV=nRT`, we can plug in what we are given

`(7.25atm)(1.52L)` = `(.406mol)[(.0821 L * atm)/(mol *K)]`(T)

rearrange everything to solve for `T`;

`T` = `((7.25atm)(1.52L))/([(.0821 L *atm)/(mol *K)] (.406mol)`

`T` = `331°K`; to get to °C, -273`K`

`T` = `58°C`
