Suppose sea water contains 3.50 weight per cent of NaCl. Calculate the molartiy of sea water

A

6.2 m

B

0.062 m

C

0.62 m

D

0.0062 m

Text Solution

Verified by Experts

The correct Answer is:
c
`NaCl` solution contains 3.5 g of NaCl in 100 g of water,
Water in solution `= 100 - 3.5 = 96.5 g = 0.0965 kg`
Molality `= (3.5)/(58.5xx0.0965) = 0.62 m`
