The volume occupied by 3.66 x atoms of lithium is 7.73
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.

Answer:
A. CaO
Explanation:
Reactant are the species that take part in and also undergoes the reaction to form species which are known as products.
Symbolic representation of the chemical reaction with the help of the formulas and symbols is known as chemical equation. In the chemical equation, reactants are written at left-hand side as well as products are expressed or written on right-hand side. The coefficients which are written before the formulas or the symbols are known as stoichiometric numbers.
Thus, in the reaction shown below:-
<u>Thus, The product of the reaction is:- CaO</u>
