Question

The initial volume of a gas cylinder is 750.0 ml. If the pressure of gas inside the cylinder changes from 840.0 mm $Hg$ to 360.0 mm $Hg,$ the final volume the gas will be :

• A. 3.60 L
• B. 4.032 L
• C. 1.750 L
• D. 7.50 L

Answer 1

The correct option is C 1.750 L

At a given temperature, $V_f=\frac{P_i{V}_i}{P_f}=\frac{840.0\times 750.0}{360.0}=1750ml=1.750L$
Thus, the final volume is 1.750 L.
