Question

A cough syrup, which comes in a concentrated syrup, contains red dye:

a) Affects the concentration of active ingredients
b) Is unrelated to its medicinal properties
c) Alters the flavor but not the color
d) Influences the syrup's shelf life

Answer 1

When a pharmacist mixes 1,550ml of syrup, 725ml of cherry flavor, and 1.25 liters of water, the total volume of the cough syrup is 3.525 liters.

Step-by-step explanation:

The red dye in a cough syrup is unrelated to its medicinal properties. The primary purpose of color additives, like red dye in this case, is to enhance the appearance of the product. They may make medications more appealing and help in distinguishing between different medications or flavors, but they do not affect the concentration of active ingredients, alter the medicinal properties, or influence the shelf life of the cough syrup.

Discussing the preparation of cough syrup, a pharmacist mixes 1,550 milliliters of syrup, 725 milliliters of cherry flavor, and 1.25 liters of water. To find the total volume in liters, first convert the milliliters to liters (since 1 liter = 1,000 milliliters) and then sum them up:
1,550 ml = 1.55 liters
725 ml = 0.725 liters
Then, add them to the volume of water:
1.55 liters + 0.725 liters + 1.25 liters = 3.525 liters.

The total volume of the cough syrup once mixed is therefore 3.525 liters.
