1.	One mole of gas occupies a volume of 200 ml. at 100 mm pressure. What is the volume occupied by two moles of this gas at 400 mm pressure and at same temperature?
Answer» <P>50 ml 100 ml 200 ml 400 ml Solution :For one MOLE of the gas `P_(2)V_(2)=P_(1)V_(1)` `V_(2)=(P_(1)V_(1))/(P_(2))=(100xx200)/(400)=50ML` `rArr"Volume of 2 moles of the gas at 400 mm PRESSURE "=2xx50=100ml`
