Question

30. The vapour pressure of methanol at
certain temperature is 1 atm. by adding a
small amount of ethyl acetate the vapour
pressure of the solution is found to be 684
mm. The relative lowering of vapour
pressure is
10.1 20.9 376 47 0.694​

Answer 1

Answer:

Po-Ps/Po = (760-684)/760= 76/760= 0.10

thus

option

a

Answer 2

Answer:

0.1

Explanation:

Here

Po - Ps =  ( 760 - 684 ) / 760

            = 76 / 760

            =  0.1
