(a)

Interpretation Introduction

Interpretation:

The concentration of ethanol in the blood is to be calculated.

Concept introduction:

The density of the substance is defined as the mass per unit volume. It is represented by $\rho$ and its unit is ${\text{kg/m}}^3$.

The formula to calculate the density of the substance is as follows:

$\text{Density of solution}=\frac{\text{Mass}}{\text{Volume of solution}}$ (1)

Mass percent is defined as the mass of a component divided by the total mass of the mixture, multiplied by 100.

(b)

Interpretation Introduction

Interpretation:

The volume of whiskey is to be calculated.
