One mole of gas occupies a volume of 200 mL at 100 mm pressure . What is the volume occupied by two mole of gas at 400 mm pressure and at same temperature ?

Options

A. 50 mL
B. 100 mL
C. 200 mL
D. 400 mL

Answer

B

Explanation

Given , `p_(1)=100mm,V_(1)=200mLandP_(2)=400mm`
From Boyle ' law , `p_(1)V_(1)=p_(2)V_(2)`
`V_(2)=(p_(1)V_(1))/(P_(2))=(100xx200)/(400)=50mL`
Volume of 2 mol gas =` 2xx50=100mL`
