Answer:
Concentration = 1.32 m
Boiling point = 
Explanation:
Let the boiling point of two solutions = T
Let the molal concentration of the two solutions= m
The relation between elevation in boiling point and molal concentration is:

i) For benzene

....(1)
ii) For carbon tetrachloride

...(2)
Equating the two equations:

Putting value of "m" in equation "1"

Answer:
0.50 M is the molar concentration of
.
Explanation:
The equilibrium constant of the reaction = 

Equilibrium concentration of
= 0.050 M
![[NO_2]=0.050 M](https://tex.z-dn.net/?f=%5BNO_2%5D%3D0.050%20M)
Equilibrium concentration of
= ?
![[N_2O_4]= x](https://tex.z-dn.net/?f=%5BN_2O_4%5D%3D%20x)
The equilibrium constant of the reaction is given aSL:
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)


0.50 M is the molar concentration of
.
True because it seems that is like a pattern it's always 6
