-How many grams of the molecule in Figure 3.2 would be required to make 2.5 L of a 1 M solution of the molecule?
(Carbon = 12, Oxygen = 16, Hydrogen = 1)

Question

Quizplus · Accepted Answer

To make a 1 M solution, you need 1 mole of the molecule per liter. For 2.5 L, you need 2.5 moles. Assuming the molecule is glucose (C6H12O6), its molar mass is 180 g/mol. Therefore, 2.5 moles would require 2.5 x 180 = 450 grams. However, since the options do not include 450, it seems there might be a mistake in the options or the molecule's identity. If the molecule is sucrose (C12H22O11), its molar mass is 342 g/mol, and 2.5 moles would require 2.5 x 342 = 855 grams, which is also not an option. The closest option is D) 150, which suggests a possible error in the problem setup or assumptions.
