50 cc of hydrogen are collected over mercury the level of which stands 20cm above the level of mercury in the trough . If the atmospheric pressure be 760mm , calculate the volume it will occupy when the level of mercury inside and outside the tube is made same .
Questions is slightly confusing,Tube vanxa troughs vanxa, Starting volume 50cubic cm xa.
U need to convert in proper unit and use some simple formulae at all😊
Use p1=560mmHg, v1=50cc
p2=760mmHg, then v2=p1v1/p2=36.84cc
