2 multiple choice 1 point
at 1400 mm hg, a gas has a volume of 350 l. what is its volume at standard pressure?
410 l
640 l
250 l
120 l

Explanation:

Step1: Recall Boyle's Law

$P_1V_1 = P_2V_2$

Step2: Define known values

$P_1 = 1400\ \text{mm Hg}$, $V_1 = 350\ \text{L}$, $P_2 = 760\ \text{mm Hg}$ (standard pressure)

Step3: Solve for $V_2$

$V_2 = \frac{P_1V_1}{P_2}$

Step4: Substitute values and calculate

$V_2 = \frac{1400 \times 350}{760} \approx 644.7\ \text{L}$

Answer:

640 L
