Calculate the number of moles of cl atoms in 2.41×1024formula units of magnesium chloride, mgcl 2 .

Answer is 8.00 mol.

Explanation;

According to the Avogadro's constant, 1 mole has 6.022 x 10²³ particles.

MgCl₂ formula units = 2.41 × 10²⁴

Hence, moles of MgCl₂ = number of formula units / Avogadro's constant

= 2.41 × 10²⁴ / 6.022 x 10²³ mol⁻¹

= 4.00 mol

MgCl₂ has 1 Mg and 2 Cl atoms. Hence, stoichiometric ratio between MgCl₂ and Cl atom is 1 : 2.

Hence, moles of Cl atoms = moles of MgCl₂ x 2

= 4.00 mol x 2

= 8.00 mol

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
