Question

Bacteria produce methane gas in sewage-treatment plants. This gas is often captured or burned. If a bacterial culture produces 60.0 mL of methane gas at 700.0 mm Hg, what volume would be produced at 760.0 mm Hg?

• A. 50.46 mL
• B. 45.38 mL
• C. 55.26 mL
• D. 59.28 mL

Answer 1

The correct option is C

55.26 mL

According to Boyle's law: $P_1{V}_1=P_2{V}_2$

Here $P_1=700mm:P_2=760mm:V_1=60mL$

$\Rightarrow V_2=\frac{700\times 60}{760}$

$\Rightarrow V_2=55.26mL$

Therefore, the volume of gas produced= 55.26 mL
