Question

A solution contain 50g of aluminium chlorine in 2 litre of solution .Find its concentration .

Answer 1

if you meant Aluminium Chloride(AlCl3) then it goes as follows:-
Molecular weight of AlCl3 = 27+(3*35.5) =133.5
Molarity(concentration)= Weight of salt/Molecular Weight*litres
=50/133.5*2
Molarity= 0.1873 M
