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) -
E.
72.5(cm^3)
Correct Answer: Option C
Explanation
(v_2=frac{v_1p_1}{p_2}=frac{20times700}{750}=18.66=18.7cm^3)
