Question

2) Hg is caustic soda ( Molar Mass = 40 ) is dissolved in water amd the solution is made to 200 ml

. Calculate the molarity of the solution .​

Answer 1

800 molarity is the solution'

Answer 2

Answer:

(a) molecular mass of NaOH= 40

number of Gram moles in 4g of NaOH= 4/40 = 0.1

volume of solution in litres = 200/1000=0.2

molarity = number of moles of solute/volume of solution in litres

0.1/0.2= 0.5 M

hope it helps you ✌️
