Question

. (a) Find molartiy of ca2+ and NO−3 in 2 M Ca(NO3)2 aqueous solution of density 1.328 g/ml.         (b) Also find mole fraction of solvent in solution..​

Answer 1

Answer:

hope it helps u dear

Explanation:

Given that

x

B

=0.2,x

A

=0.8

Now,

Molality (m)=

x

A

×M

A

x

B

×1000

=

0.8×18

0.2×1000

=13.88m

where,

M

A

= molar mass of solvent
