Insulin is dissolved in a suitable solvent and the osmotic pressure (pi) of solutions of various concentration (g//cm​^3​) C is measured at 20^@C. The slope of a plote of pi against C is found to be 4.65xx10^(-3) ​. The molecular weight of the insulin is :-

Answer»

`3xx10^5`
`9xx10^5`
`4.5xx10^5`
`5.16xx10^6`

SOLUTION :`pi=w/mxx(RT)/V`
slope = `(RT)/M`
`M=(RT)/"slope"=(0.0821xx293)/(4.65xx10^(-3)xx10^(-3))=5.16xx10^6` g
