Answer : The molality of solution is, 5.69 mole/L
Explanation :
The relation between the molarity, molality and the density of the solution is,
where,
d = density of solution = 1.25 g/mL
m = molality of solution = ?
M = molarity of solution = 4.57 M
= 98 g/mole
Now put all the given values in the above formula, we get
Therefore, the molality of solution is, 5.69 mole/L
