\(500cm^{-3}\) of a gas is collected at 0°C and at a pressure of 72cm of mercury. What is the volume of the the gas at the same temperature and at a pressure of 76cm of the same mercury?
\(\frac{76\times500}{72}cm^3\)
\(\frac{72\times500}{76}cm^3\)
\(\frac{72\times76}{500}cm^3\)
\(\frac{76}{72\times500}cm^3\)
\(\frac{72}{76\times500}cm^3\)
คำอธิบาย
\(P_1V_1=P_2V_2, V_2= \frac{72\times500}{76}cm^3\)
