Question

fill in the missing words
if the gas pressure inside a 5.0 l container with 0.21 moles of oxygen is 1.0 atmosphere, the temperature of the gas is degrees celsius.

Explanation:

Step1: Recall ideal gas law

$PV = nRT$

Step2: Solve for temperature $T$

$T=\frac{PV}{nR}$, where $P = 1.0\ atm$, $V=5.0\ L$, $n = 0.21\ mol$, and $R = 0.0821\ L\cdot atm/(mol\cdot K)$
$T=\frac{1.0\times5.0}{0.21\times0.0821}\ K$
$T=\frac{5.0}{0.017241}\ K\approx290\ K$

Step3: Convert from Kelvin to Celsius

$T_{Celsius}=T - 273$
$T_{Celsius}=290 - 273= 17$

Answer:

17
