Practice: Converting between Moles and Grams

Converting between moles and grams is a fundamental chemistry skill. In this video there are six problems with explanations. The problems start easy and then become more difficult. At the end of the video you should be comfortable converting from moles to grams and grams to moles. One method to mole conversions is to use something called the Mole Map. This provides a visual tool to know when to multiple and when to divide. The Mole Map is also useful for conversions between the mole and liters as well as atoms and molecules.

The conversion factor used is the molar mass of the element or compound. This is the preferred method for mole conversions. Conversions should be automatic (you don’t really need to think about it much to find the answer). This requires lots of practice converting between moles and grams. The more you practice the less effort that is required, and you can focus on solving the bigger chemistry problems (like reaction stoichiometry). The video is organized like a worksheet where you answer the problems and the check your answers.
