A student wanted to investigate the concentration of glucose in different energy drinks. The student first produced four glucose solutions of different, known concentrations by diluting a 4.0 mM glucose solution. The volumes of distilled water and glucose solution added to each test tube can be seen in Table 1. The total volume of each solution was 10 Table 1 Final concentration of glucose solution/ mM Volume of distilled water/ cm Volume of glucose soluti- 4.0 0.0 10.0 5.0 5.0 7.5 2.5 1.25 8.75 Complete Table 1 by filling in the three blank spaces with the correct final concentrations of glucose solution.
