Chapter 1, Problem 70P

Interpretation Introduction

Interpretation:

The mass of $1\text{ gallon}$ of gasoline is to be calculated.

Concept introduction:

Density is defined as mass per unit volume. Mass and volume are physical quantities and the units of mass and volume are fundamental units. Density is the ratio of mass to the volume. The unit of volume is derived from the units of mass and volume. The SI unit of density is ${\text{kg/m}}^{\text{3}}$ . The formula to calculate density is,

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

The relation between liter and milliliter is,

  $1\text{ L}=1000\text{ mL}$

The relation between liter and gallon is,

  $1\text{ gallon}=3.79\text{ L}$

The relation between kilogram and gram is,

  $1\text{ kg}=1000\text{ g}$
