Percent Composition Common Mistakes

Don't make these common mistakes with percent composition! Here, we'll talk about two common mistakes that students often make when they are working through percent composition problems. The first mistake involves calculation of the total molar mass of an element in the compound. The second mistake happens when students forget to multiply their final answer by 100%.

You would take your time to make the set up including pre written materials and paper cut out in order to efficiently provide the necessary info. I highly respect your effort for doing that

I'm a chemistry teacher, and I use your videos almost exclusively when referring my students to online review videos.

What if the percentage composition has parenthesis for example Mg(NO3)2

You have to multiply by 100, not 100%. Multiplying by 100% would be the same as multiplying by 1 which is the same as doing nothing.
