    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) 1.750 L            

    B) 3.60 L

    C) 4.032 L            

    D) 7.50 L

    Correct Answer: A

    Solution :

    [a] According to Boyle's law \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{P}_{1}}}{{{P}_{2}}};\frac{750}{{{V}_{2}}}=\frac{360}{840}\] \[{{V}_{2}}=1750mL=1.750L\]
