The mass of a piece of galena in kilograms ( kg ) is to be calculated. Also, a road map for the solution is to be drawn. 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 kg/m 3 . The formula to calculate density is, Density = Mass Volume Mass is a physical quantity and its SI unit is kilograms ( kg ) . It is the measure of the quantity of the matter present in an object. The other units of mass are grams, milligrams. Volume is a physical quantity and its SI unit is cubic meter ( m 3 ) . The other units of the volume are liter, milliliter, cubic decimeter, microliter.

Interpretation Introduction

Interpretation:

The mass of a piece of galena in kilograms (kg) is to be calculated. Also, a road map for the solution is to be drawn.

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 kg/m3. The formula to calculate density is,

Density=MassVolume

Mass is a physical quantity and its SI unit is kilograms (kg). It is the measure of the quantity of the matter present in an object. The other units of mass are grams, milligrams.

Volume is a physical quantity and its SI unit is cubic meter (m3). The other units of the volume are liter, milliliter, cubic decimeter, microliter.
