Question

A 200 cc flask contains oxygen at 200mm pressure and a 300 cc
flask contains Nitrogen at 100mm pressure. The two flasks are
connected so that each gas occupies the combined vo The
total pressure of the mixture in mm is​

Answer 1

Explanation:

ANSWER

According to Dalton's law of partial pressure,

P

1

V

1

+P

=PV

total

Here, P

1

=200cc,P

2

=300cc,V

1

=200mm,V

2

=100mm

So, here total volume is 500mm

∴200×200+300×100=P×500

P=140 mm
