A group of students in an organic chemistry course performed a lab experiment in which they synthesized a colorful compound from not-especially-colorful starting materials. This synthesis required 3mol of the starting material, with formula C8H10NBr, for every mole of product desired; and the group started with 5.0g of starting material (all other reagents in excess). At the conclusion of their reaction, they had 8.0mL of solution, intensely colored due to the presence of their product. The concentration of colorful compounds...
