The solution containing `4.0gm` of a polyvinyl chloride polymer in `1` litre dioxane was found to have an osmotic pressure `6.0xx10^(-4)`atmosphere at `300K`,the value of R used is `0.082`litre atmosphere`"mole"^(-1)K^(-1)`.The molecular mass of the polymer was found to be

A

`3.0xx10^(2)`

B

`1.6xx10^(5)`

C

`5.6xx10^(4)`

D

`6.4xx10^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`piV=(w)/(m)RT`
`therefore 6xx10^(-4)xx1=(4)/(m)xx0.0821xx300,m=1.64xx10^(5)`.
