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

For the ideal solutions, which of the following condition is suitable?

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).

An example of a near-ideal solution is:

The solution which shows negative or positive deviation from Raoult's law is called:

$A$ liquid mixture is an ideal solution, if
$(I)$ It obeys ideal gas equation
$(II)$ It obeys Raoult's law at all concentrations
$(III)$ Solute - solute, solute - solvent and solvent - solvent interactions are similar
