Question

20 gm of naoh dissolved in water to make 120 gm of solution calculate molarity of the solution​

Answer 1

Explanation:

We know,

Molality =

weight of solvent (kg)

moles

Molality =(

molecular weight

weight

)×

(volume×density)

1000

[Note: density =1 gm/cm

3

]

Molality =

40

20

×

500

1000

×1=1 m
