Question
How do you make a 10, 20, and 30% solution of sucrose?
b. A student measured out 0.509g of galactose and dissolved it in 25.0mL of water. 10.0 cm of sample was added to the cell, producing an angle of 204.4. If the blank's angle was 202.7, what is the observed angle of rotation for the sugar solution, the specific rotation of the sugar, and the percent difference.
c. Calculate the concentration of sucrose using the following information: blank's angle = 180.0, sample height = 9.7cm, and sample's angle = 186.3.
