Calculate equivalent mass of KCl mgcl2 6 h2o-- a) M/3 b) M c) M/6 d) M/12
1 Answer
shivani
option a)
equivalent mass is M/n factor
n factor for the above compound is 3(count either total negetive charge or total positive charge.water of crystallistaion is not taken into consideration while taking out equivalent mass,so if i use positive charges we find that we get 1 positive charge for K AND 2 Positive charge for cl ,so the total charge is 3,hence n factor is 3)so equivalent mass is M/3
