The volume occupied by water molecules in vapour phase is (1 – 10-4) dm3, that is approximately 1 dm3.

Dear student,

Please find the solution to your problem below.

There seems to be some missing data from your question.

Taking Vapour pressure of H₂O at 300 K = 3170Pa

Volume of water added = 10^-4 dm³

Now, The volume occupied by water molecules in vapour phase is (1 – 10^-4) dm3, that is approximately 1

Now, P_vapV = n_H2ORT

3170 x 1 x 10^-3 = nH₂O x 8.314 x 300

or, n_H2O = 3170 x 10^-3/(8.314 x 300) = 1.27 x 10^-3

Thanks and regards,

Kushagra

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask andthe equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
