The density of a substance is defined as the mass of the substance per unit volume. It is often denoted by the symbol ρ
The density of a substance is given by,
The mass of a substance is the measure of the amount of matter present in it. It is generally measured in grams (g) or kilograms (kg).
The volume of a substance is defined as the amount of 3D space occupied by it.
<h3>What is Mole Concept?</h3>It is a concept which uses mole as a unit to measure the number of atoms, molecules or ions.
A mole is defined as the amount of substance which has the same number of elementary particles as there are atoms in 12 grams of
1 mole = Avogadro's number = 6.022 x atoms
Molar Mass of Lithium = 6.94 g/mol
1 mole of Lithium has 6.022 x atoms
3.66 x atoms of lithium has molar mass =
Substitute in density formula,
= 7.73
Therefore, 3.66 x atoms of lithium occupies 7.73
of volume.
