The figure belоw cоntаins the fоllowing substаnces: 6.022 X 1023 molecules of sucrose, C12H21O11 6.022 X 1023 molecules of sulfur, S8 6.022 X 1023 formulа units of copper(II) sulfate pentahydrate, CuSO4.5H2O 6.022 X 1023 atoms of copper Which, if any, contains the largest amount of moles of the substance? Following is a description if the figure is not visible: it shows four beakers containing four different solids. From left to right the beaker size and content are: 500-mL beaker 3/4 filled with white sucrose 150-mL beaker 3/4 filled with pale yellow sulfur 250-mL beaker almost filled with blue copper(II) sulfate pentahydrate 50-mL beaker 1/2 filled with copper pellets (spheres)
