Question

if 1 litre of a gas a at 600 mm in 0.5 litre of gas B at 800 mm are taken in earth to litre bulb the resulting pressure is​

Answer 1

Answer:

THE ANSWER IS 500

Explanation:For gas A,

P = 600 mm

V = 1 L

No. of moles of A =  

RT

PV

​  

=  

RT

600×1

​  

=  

RT

600

​  

 

For gas B,

P = 800 mm

V = 0.5 L

No. of moles of B =  

RT

PV

​  

=  

RT

800×0.5

​  

=  

RT

400

​  

 

Total no. of moles =  

RT

600

​  

+  

RT

400

​  

=  

RT

1000
