Heptane and octane form an ideal solution. At $373 \, K$,the vapour pressures of the two liquid components are $105.2 \, kPa$ and $46.8 \, kPa$ respectively. What will be the vapour pressure of a mixture of $26.0 \, g$ of heptane and $35 \, g$ of octane (in $, kPa$)?

If liquids $A$ and $B$ form an ideal solution,then which of the following is true?

Two statements are given below:
Statement-$I$: Liquids $A$ and $B$ form a non-ideal solution with positive deviation. The interactions between $A$ and $B$ are weaker than $A-A$ and $B-B$ interactions.
Statement-$II$: For an ideal solution,$\Delta_{mix} H = 0$ and $\Delta_{mix} V = 0$.
The correct answer is:

What are the values of $\Delta H_{mix}$ and $\Delta V_{mix}$ for an ideal solution?

When does a mixture containing components $A$ and $B$ show negative deviation from Raoult's law?

Which of the following is not correct for an ideal solution?
