Chemistry grade 11 NEB


#1

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 .


#2

Questions is slightly confusing,Tube vanxa troughs vanxa, Starting volume 50cubic cm xa.


#3

Its easy
U need to convert in proper unit and use some simple formulae at all😊


#4

Use p1=560mmHg, v1=50cc
p2=760mmHg, then v2=p1v1/p2=36.84cc
