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?

  • A. 2.5\(cm^3\)
  • B. 15.5\(cm^3\)
  • C. 18.7\(cm^3\)
  • D. 21.4\(cm^3\)

Correct Answer: C. 18.7\(cm^3\)

Explanation

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