Explanation / Answer

(1)Number of moles of CCl4 (Carbon Tetra Chloride) = 1.84 mole

Number of molecules = Number of moles * Avogadro’s number = 1.84 * 6.023 * 10^23 molecules

Since number of carbon atoms in CCl4 is 1 , Hence number of Carbon atoms present = 1*1.84 * 6.023 * 10^23 = 11.082 * 10^23

(2)Number of molecules of CCl4 = 5.95 * 10^22

Number of moles of CCl4 = (5.95 * 10^22) / (6.023 * 10^23) = 0.0988 mole

Since number of Cl atoms in CCl4 is 4, hence number of moles of Cl present = 4 * 0.0988 mole = 0.3952 mole
