A polarimeter tube of length 0.21m contains sugar solution of specific rotation 0.01 rad `m^(-1)kg^(-1)m^(3)` concentration. If the produced is `36^(@)`, calculate the concentration of the solution. The solution is the tube is poured into a clean beaker and equal amount of water id added to it. The tube is then filled with the diluted solution. Calculate the angle of rotation produced.

Ammonia contains 82.32% of nitrogen and 17.65 % of hydrogen . Water contains 88.90% of oxygen and 11.10% of hydrogen . Nitrogen trioxide contains 63.1
In `NH_(3), 17.65 g` of H combine with N=82.35 g `therefore` 1 g of H combine with H`=(82.35)/(17.65) g` =4.66 g In `H_(2)O, 11.10 g` of H combine with O=88.90...
