Question

The molality of solution containing 5 g NaOH in 500 g of
water is
O 0.1 m
nB
O 0.25 m
O 0.5 m
O im​

Answer 1

Answer:

0.25

Explanation:

this is the correct answer

Answer 2

Answer:

0.25m

Explanation:

given: weight of solute = 5g

           molecular weight of solute = 40g

           weight of solvent = 500g

molality     =                 given weight of solute

                ____________________________________        *100

                molecular weight of solute* weight of solvent

molality = 5*100/40*500

             = 0.25m
