Measuring Mass and Volume

Part of the Food Chemistry and the Lab section of Coddy's Chemistry journey. Lesson 18 of 27.

A balance gives grams. A measuring cylinder is quick; a pipette gives one exact volume; a burette any volume to 0.05 mL.

Read the bottom of the meniscus, eye level with it.

Weigh in grams, count in moles: $m = n \times M$ .

Challenge

A student needs $0.2\ \mathrm{mol}$ of sodium chloride, NaCl, molar mass $58.5\ \mathrm{g/mol}$ . What mass m should the balance show?

Try it yourself

Solve for $m$
