A balloon at STP contains $1$ mol of ideal gas. Using $R = 8.314$ J/(mol K) and $T = 273$ K, the product $PV$ is approximately:
A$8.314$ J, ignoring the factor of temperature here
B$2270$ J, since $PV = nRT = 1\cdot 8.314\cdot 273$
C$273$ J, the temperature alone in joules
D$32.5$ J, dividing temperature by gas constant
Answer & Solution
Correct answer: B. $2270$ J, since $PV = nRT = 1\cdot 8.314\cdot 273$
$PV = nRT = 1\cdot 8.314\cdot 273 \approx 2270$ J.
