Real-Life Math -- Solution

How much fragrance (by weight) will be added to the base?

Weight of added fragrance:

1.5 kg x 0.06 = 0.09 kg

You'll be adding 0.09 kg of fragrance, or 90 grams.

Perfumers often use math to calculate volumes and concentrations. Most of their work is creating scents their noses like, not using formulas, so math plays a small role.

Often, perfumers need to dilute their mixtures. For example, a finished perfume contains fragrant oils and chemicals at a certain percentage in an alcohol solution, such as 10 or 20 percent.

"In building the formulation, certain ingredients are so powerful that we use them in dilution," perfumer Claudette Belnavis says. "It's really elementary."

Mathematics can play a larger role early in a perfumer's career. Many perfumers start as lab technicians. Often they're involved in quality control, making sure ingredients are pure and have the right scent. In the lab, math is used more. Also, good math skills are needed to get a chemistry degree, which many perfumers have.
