A graduated tube, sealed at the upper end has a mercury leveling bulb connected to the lower end. the gas volume is 25.ml, when the mercury level is the same in both ends. the barometric pressure is 732 mm Hg. What is the gas volume when the mercury level on the open side is 10 cm above the mercury level in the closed side?

21.99 ml

p1v1=p2v2
p1=732mmhg
v1=25ml
p2=732+100=832mmhg
v2=?
732*25=832*v2
v2=21.99

Ana - if the mercury rises in the open end, then it must drop in the closed end. Since the closed end presumably holds the 25 ml of gas, the volume would have to increase, it couldn't be a smaller number like 21.99. It all depends on how you picture this contraption I guess.
