Question

Calculate the no : of ions in 1.77 moles of magnesium chloride

Answer 1

The number of particles ( ion) = Number of moles of particles x Avogadro number
 
N = n x Avogadro no.
   
           = 1.77 x 6.022 x 10^23
           = 1.065894 x 10^24

Answer 2

Given,

No. of moles (n) = 1.77

To calculate no. of ions,

Formula,

No. of moles (n) = No. of particles (ion) (N) / Avogardo number (NO)

No. of particles (ion) (N) = No. of moles (n) * Avogardo number (NO)

N = n * NO

N = 1.77 * 6.022 * 10^23

N = 10.65894 * 10^23

N = 1.065894 * 10^24
