A 300 mm long tube containing 60 cm^(3) ...

A 300 mm long tube containing 60 `cm^(3)` of sugar solution produces an optical rotations of `10^(@)` when placed in a saccharimeter. If specific rotation of sugar is `60^(@)` calculate the quantity of sugar constained in te tube solution.

Text Solution

Verified by Experts

`l=300mm=30cm=3` decimeter, `theta=10^(@),[alpha]_(A)^(T)=60^(@)`, volume of solution `=60cm^(3)`
`theta=[alpha]_(lamda)^(T)lCimpliesC=(theta)/([alpha]_(lamda)^(T)l)=(10^(@))/(60^(@)xx3)=(1)/(18)gcm^(-3)`
Quantity of sugar contained `=(1)/(18)xx60=3.33g`
