Identify the mixture that shows positive deviations from Raoult's Law.

Which condition is not satisfied by an ideal solution?

In a mixture of $A$ and $B$ components,the solution shows positive deviation from Raoult's law when:

At $363 \ K,$ the vapour pressure of $A$ is $21 \ kPa$ and that of $B$ is $18 \ kPa$. One mole of $A$ and $2 \ moles$ of $B$ are mixed. Assuming that this solution is ideal,the vapour pressure of the mixture is $....... \ kPa$. (Round off to the Nearest Integer).

For an ideal solution of two components $A$ and $B$,which of the following is true?

On mixing $10 \ mL$ of acetone with $40 \ mL$ of chloroform,the total volume of the solution is
