Question

if 7.6 l of oxygen at 845 mm hg are compressed to 387 mm hg at constant temperature. what is the new volume, in l? round to 1 decimal place

Explanation:

Step1: Identify the relevant law

Boyle's law states $P_1V_1 = P_2V_2$ for a gas at constant temperature.

Step2: Assign values

Let $V_1 = 7.6$ L, $P_1=845$ mmHg, $P_2 = 387$ mmHg, and we need to find $V_2$.

Step3: Rearrange the formula

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

Step4: Substitute values

$V_2=\frac{845\times7.6}{387}=\frac{6422}{387}\approx16.6$ L.

Answer:

16.6
