Answer to Question #116137 in General Chemistry for Chelse Bell

Question

A gas measuring 525 mL is collected at 104.66 kPa. What volume does this
gas occupy at 99.33 kPa?

Answer 1

$P_1=104.66 \ KPa;V_1=525\ ml$ ;

$P_2=99.33\ K Pa;V_2=?$

Using Boyle's law,

$P_1V_1=P_2V_2\implies 104.66\times 525=99.33\times V_2\implies V_2=553.17\ ml$
