A gas at pressure 912 mm of Hg has volume 450 cm3. What will be its volume to 1200 cm3. What will be it's Pressure in mm of Hg?
I assume the question should read, "A gas at pressure 912 mm of Hg has volume 450 cm3. If its volume changes to 1200 cm3. What will be it's Pressure in mm of Hg?"
Use P1V1 = P2V2
P1 = 912 mm
V1 = 450 cc
P2 = ?
V2 = 1200 cc
