Question

If 10^-4 dm^3 of water is introduced into a 1.0 dm^3 flask at 300 K,how many moles of water are in the vapour phase when equilibrium is established?(Given, vapour pressure of H20 at 300 K is 3170 Pa,R=8.314 J/K/mol)

Answer 1

Answer:

If 10-4 dm3 of water is introduced into a flask at 300 K, how many moles of water are in the vapour phase when equilibrium is established?

( Given : Vapour pressure of H2O at 300 K is 3170 Pa ;R = 8.314 JK-1 mol-1 )

Option 1) 1.27 × 10-3 mol Option 2) 5.56 × 10-3 mol Option 3) 1.5 × 10-2 mol Option 4) 4.46 × 10-2 mol
