If 16 g of Ca(OH)2 has been dissolved in 4,000 ml water resulted in 4.16 Kg solution of 4.06 liter volume then calculate concentration of solution in molarity, normality, molality, mole fraction of solute, w/w%, w/v% and ppm.
do you think there is a problem is the question? if not pls solve it

4000 ml of water weights 4 kg. If you add 16 g of anything, you should have a 4.016 kg solution, not 4.16. So, yes, there appears to be a problem with the problem. Further, it seems unlikely that adding 16 g of anything to 4L of water would result in 4.06L final volume - more likely it is 4.006. (Or, perhaps, the added mass is 160 g?)
You get molarity by dividing the number of moles of Ca(OH)2 (approximate molar weight of 74 g/mole) by the final volume. Normality is twice the molarity, in this case. The other numbers follow once you have the correct values.
Hope this helps
