Question

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

Answer 1

Explanation:

in AlCl3 Wt. of Al is 27gm and that of chlorine is 106.5gm

so in 133.5gm of AlCl3 have 106.5gm of Cl

therefore, 75gm of AlCl3 will have 59.83gm of Cl

For finding no. of ions,

no. of moles of Cl*Avogadro's no. * no. of Cl in AlCl3

= 59.83/35.5 * 6.02*10²³ * 3

=30.43*10²³

or 5.05*Nà
