If atomic mass of nitrogen is 14u and atomic mass of Oxygen is 16u, what is the molar mass of Nitrous oxide?

A

44u

B

40u

C

30u

D

46u

Text Solution

Verified by Experts

The correct Answer is:
B, C
A `1.5m` solution ………….
Let mass of solvent in `1.5m `solution `= m_(1) kg` and let mass of solvent in `3m` solution `=m_(2) kg`. Therefore molality of resulting solution `= (1.5m_(1)+3m_(2))/(m_(1)+m_(2)) = 2`
`:. (m_(1))/(m_(2)) = (2)/(1)`
Therefore required radio `= (109)/(59)` .
