Question

A solution contains 2gms of the solute in 25ml. of Solution at 25°C. What will be the gm/ltr strength of the solution?​

Answer 1

Answer:

0.25 M

Explanation:

The molecular weight of NaOH is 40 g/mol.

The number of moles of NaOH

40 g/mol

5 g

=0.125 moles.

500 ml water corresponds to0.500 L.

The molarity of the solution =

0.500 L

0.125 moles

=0.25 M
