Question

The density of 4% NaOH solution is 1.02 g/m/. What is the molality of the
solution?
​

Answer 1

Answer:

(C) 0.75 M

(0) 0.25 M

100 MH,SO,

solution is mixed with 100 ml of 9.8 % (w/w) H,50, solution (d = 1 g/m, then

Al concentration of solution remains same

volume of solution become 200 ml

Il mass of H So, in the solution is 98 g

o mass of 1,50. In the solution is 19.68
