Question

At a constant temperature, a gas occupies a volume of 200 ml at a pressure of 0.720 bar. It is subjected to a total pressure of 0.900 bar. What is the resulting volume of the gas?

• A. 160 ml
• B. 250 ml
• C. 4 ml
• D. 100 ml

Answer 1

The correct option is A 160 ml

$P_1{V}_1=P_2{V}_2$
$\Rightarrow 0.72\times 200=0.90\times V_2$
$\Rightarrow V_2=\frac{0.72\times 200}{0.90}=160ml$
