A gas occupies a volume of 0.2 L at 176 mm Hg. What volume will the gas occupy at 760 mm Hg?

nignag [31]

Answer:

$V_2=0.046L$

Explanation:

Hello,

In this case, we apply the Boyle's law as an inversely proportional relationship allowing us to understand the pressure-volume behavior as shown below:

$P_1V_1=P_2V_2$

In such a way, solving for the final volume V2, we obtain:

$V_2=\frac{P_1V_1}{P_2}=\frac{0.2L*176mmHg}{760mmHg} \\\\V_2=0.046L$

Best regards.
