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
