A fixed mass of gas occupies a volume of 20\(cm^3\) at a fixed pressure of 700mmHg. Assuming that the temperature remains constant, what will be the volume of the gas at 750mmHg?
2.5\(cm^3\)
15.5\(cm^3\)
18.7\(cm^3\)
21.4\(cm^3\)
72.5\(cm^3\)

\(v_2=\frac{v_1p_1}{p_2}=\frac{20\times700}{750}=18.66=18.7cm^3\)
