Interpretation:
The volume of wine present in
Concept introduction:
Several concentration units may be used to express the concentration. It is often useful to express the concentration in terms of percentage. This can be expressed as the amount of solute in grams dissolved in
The formula to calculate the volume /volume percent is as follows:

- A 12-oz (355-mL) Pepsi contains 38.9 mg caffeine (molar mass = 194.2 g/mol). Assume that the Pepsi, mainly water, has a density of 1.01 g/mL. For such a Pepsi, calculate: (a) its caffeine concentration in ppm; (b) its molarity of caffeine; and (c) the molality of caffeine.arrow_forwardButylated hydroxytoluene (BHT) is used as an antioxidant in processed foods.
