Calculate the molarity of the yellow stock solution. 10.00 L of the stock solution contains 0.1991 g of Yellow #5 food coloring with molar mass = 534.36 g/mol. B. Calculate the concentration of the yellow stock solution parts per million, ppm. Recall: ppm = (mg of solute)/(Liters of Solution) C. Consider the dilutions used to make the solutions and calculate the ppm of each standard solution. (Use C1V1= C2V2) D. Explain why ppm is more convenient than molarity for the units of concentration here.

In this question, we will be delving into various aspects of concentration calculations, specifically focusing on a yellow food coloring solution known as Yellow #5. We will explore how to determine the molarity and concentration of this solution in parts per million (ppm). Additionally, we will consider the dilution of the stock solution to create standard solutions with known concentrations. Lastly, we will discuss the practicality and advantages of using ppm as a unit of concentration in this particular context.
