Chapter 4, Problem 100IAE

Interpretation Introduction

(a)

Interpretation:

The volumes of the pure liquid samples and the solution should be calculated to show that the pure liquid volumes are not additive.

Concept introduction:

Volume of a pure liquid or a solution is calculated by dividing the mass by the density value.

$\text{Volume=}\frac{\text{Mass}}{\text{Density}}$

Interpretation Introduction

(b)

Interpretation:

The molarity of methanol in the solution should be calculated.

Concept introduction:

The molarity of a solute in a solution is determined by dividing the moles of solute by the volume of the solution in liter.

$M=\frac{n}{V\left(\text{L}\right)}$

Here, n is number of moles of solute and V is volume of solution in L.
