If this is wrong then use the formula in this answer
Explanation:
molality=
kilograms of solvent
moles of solute
moles of NaOH=
Mass of NaOH
Weight of NaOH
=
40
25
=
8
5
=0.625
kilograms of H
2
O=
1000
Weight of H
2
O
=
1000
100
=0.1
∴molality=
kilograms of solvent
moles of solute
=
0.1
0.625
=6.25m
Hence, the correct answer is 6.25.
