Question

calculate the number of chlorine ions in 75g of aluminum chloride? ​

Answer 1

Answer:

Explanation:

Formula of Aluminium Chloride is AlCl3

Molar mass of AlCl3 is 133.5g

Therefore there are 3 moles of chlorine atoms in one mole of AlCl3

3 moles = 18.066  * 10^23 atoms

(Given Mass/Molar mass) = (No of atoms in given mass/No of atoms in 1 mole)

So, the number of chlorine ions in 75g of aluminium chloride is:-

75/133.5 = no of atoms/18.066 * 10^23

no of atoms = (75 * 18.066 * 10^23)/(133.5)

                    = 1.011 * 10^24 atoms      (approx)
