Concept explainers
Interpretation:
Between a sucrose solution (20 g sucrose in 1 L) and a glucose solution (20 g glucose in 1 L) which is more concentrated must be explained.
Concept introduction:
Molecular weight of sucrose is 342 g/mol and that of glucose is 180 g/mol.
Answer to Problem 7E
20 g glucose in 1L solution is more concentrated as compared to 20 g sucrose in 1 L solution.
Explanation of Solution
Molarity of glucose in 1 L of the solution will be equal to the number of moles which can be calculated from its mass and molar mass as follows:
Similarly,
Thus molarity of glucose solution is higher as compared to sucrose solution.
Glucose solution is more concentrated.

- Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4- 1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer.
