A solution containing 4.0 g of PVcC in 2 liter of dioxane (industrial solvent ) was found to have an osmotic pressure 3.0 x `10^(-4)`atm at `27^(@)C`. The molar mass of the polymer (g/mol) will be :

A

`1.6 xx 10^4`

B

`1.6 xx 10^5`

C

`1.6 xx10^3`

D

`1.6 xx 10^2`

Text Solution

Verified by Experts

The correct Answer is:
B
`M_B = (W_BxxR xxT)/(pi xxV) = (4 xx 0.0821 xx300)/(3 xx 10^(-4) xx 2)`
`~~ 1.6 xx10^5`
