7.2 A focus on calculating mass from molarity and volume
If you had to prepare a 5 ml aliquot of 20 mM glucose for each of pair of students in a class of 120, how much glucose would you need to weigh out? The molecular weight of glucose is 180.156 g mol–1.
Mass from Molarity and Volume
Vy Hoang is senior laboratory technician. Part of her work involves preparing reagents and materials for teaching laboratories. The problem above is a typical one she must solve on every day, and she would have solved many similar problems during her time in research. Watch an interview with Vy to see how this kind of problem is solved but also to see how to develop the quantitative mindset required to do routine laboratory work.
