Question

The volumes of two vessels at same temperature are in the ratio of 2:3.one vessel contains h2 and other n2 at 600mm and 900mm respectively.

Answer 1

The question is incomplete. The correct question is:

The volumes of two vessels at same temperature are in the ratio of 2:3.one vessel contains h2 and other n2 at 600mm and 900mm respectively.  Find the resulting pressure if both the vessels are joined together.

Answer:

Let the Vessel A contain H₂ and let Vessel B contain N₂.

Vessel A = H₂ = 200 ml

Vessel B = N₂ = 300 ml

Now total Volume = 200 + 300 = 500 ml

So calculating Pressure now,

Vessel A = ( 200 / 500 ) * 600 mm

=> Vessel A = 0.4 * 600 = 240 mm of Hg

Vessel B = ( 300 / 500 ) * 900 mm

=> Vessel B = 0.6 * 900 = 540 mm og Hg

Now adding up the pressures we get,

=> 240 mm + 540 mm = 780 mm of Hg

Hence the total pressure exerted after joining the two vessels is 780 mm of Hg.
