Calculate the specific rotation of sugar solution from the following data: length of the polaimeter tueb=0.21 concentration of sugar solution = 80kgm^(-3) angle of rotation = 10^(@)

Cholesterol, when isolated from natural sources, is obtained as a single enantiomer. The observed rotation alpha of a 0.3 g sample of cholesterol in 5mL of chloroform solution contained in a 10 cm polarimeter tube is -0.78^(@) . Calculate the specific rotation of cholesterol. A sample of synthetic cholesterol was prepared consisting entirely of (+)-cholesterol. This synthetic (+)-cholesterol was mixed with some natural (-)-cholesterol. The mixture had a specific rotation [alpha]_(D)^(20) " of " -13^(@). What fraction of the mixture was (+)-cholesterol ?

Calculate the work done in rotating a magnet of pole strength [10^(-2)] Ampere-m and magnetic length 10 cm through an angle of 60° from its position along the magnetic, meridian. (B = 200T)

80 gm of impure sugar when dissolved in a litre of water gives an optical rotation of 9.9^(@) when placed in a tube of length 20 cm. If concentration of sugar solution is 75 gm/litre then specific rotation of sugar is :

A cylindrical tube of light 0.2m and radius R with sugar solution of concentration 'C' produce a rotation of theta in the plane of vibration of a plane polarized light. The same sugar solution is transferred to another tube of length 0.3m of same radius. The remaining gap is filled by distilled water. Now the optical rotation produced is

A tube of sugar solution 20 cm long is placed between crossed nicols and illuminated with light of wavelength 6xx10^(-5) cm If the optical rotation produced is 13^(@) and the specific rotation is 65^(@) determine the strength of the solution
