Question

The total number of ions present in 1 ml of 0.1 m barium nitrate solution is

Answer 1

hey

So, 1 mole in a liter has 6.02 * 10^23 'particles' of Ba(N03)2, each 'particle' has 3 ions, so the total numer of ions is 
18.06 * 10^23 = 1.806 * 20^24 ions. 

But the concentration is 0.1 Molar, so there are 1.806*10^23 ions in a liter of 0.1 Molar Barium Nitrate 

But you want to know the amount in 1/1000 of a liter, so that is 
1.806*10^20 ions.
