Mass is a fundamental property of matter that represents the amount of matter in an object. It is a measure of an object's resistance to acceleration when a force is applied.

Option 1: "The amount of space the object occupies" - This describes volume, not mass - Volume is a measure of space, while mass is a measure of matter - Incorrect definition Option 2: "Its ratio of weight to volume" - This is incorrect because: * Weight depends on gravity * Mass is independent of gravitational field * Density (mass per unit volume) is different from this description - Incorrect definition Option 3: "The quantity of matter the object contains" - This is the most scientifically accurate definition - Mass represents the total amount of matter in an object - Remains constant regardless of location or gravitational field - Measured in units like kilograms (kg) Option 4: "The force of gravity acting on the object" - This describes weight, not mass - Weight changes with gravitational field - Mass remains constant everywhere in the universe

The key characteristics of mass are: - Represents the amount of matter - Constant regardless of location - Fundamental property of an object
