Q A 300 mm long tube containing 60 cc of sugar solution produces a rotation of 90 when placed in a polarimeter If the specific rotation is 600, Compute the quantity of sugar contained in the solution

Data : l = 300 mm = 30 cm = 3 decimetre

θ = 9o ; S = 60o ; v = 60 cc

m = ?

Solution : S = θ/ l× c

=θ/ l× (m/v)

m = (θ×v) / l s

= 9 × 60 / 3 ×60

m = 3 g
