A student wants to estimate the glucose concentration in a sample by collecting, drying, and weighing the precipitate formed during a Benedict's test. The concentration of glucose can then be read off a calibration curve as shown in Fig. 21.1.
The student collects the precipitate from the Benedict's test of a sample.
The wet mass of the precipitate is 16 g, which is 75% water.
Calculate the concentration of glucose in the sample.
Use Fig. 21.1 to support your answer.
