This is Ken Kuwako, the Science Trainer. Every day is an experiment.<\/strong><\/span><\/p>\n

Have you ever been following a recipe and wondered what “a pinch of salt” really means? In the world of chemistry, we have a similar situation with several ways to express “concentration,” and scientists choose the best one for the job. Today, let’s explore how to switch between two of these units: mass percent concentration, which you might remember from science class, and the more professional molar concentration (molarity). Understanding these calculations will make the world of chemistry feel much more approachable, and your experiments will become more fun\u2014and safer!<\/p>\n
