In this video, we look at how to calculate the percentage by mass of an element in a compound. This is a relatively straightforward topic but it's very important that you can do it.

Love the new intro!

[@candy_playz2773]

How come you are re-making these videos? Are they in the chemistry playlists as I'm currently making notes for quantitative chemistry from there for my mocks :)

[@Freesciencelessons]

I'm remaking them to improve the sound quality. The content does not change. All the videos will be in the usual playlists.

Got my GCSE chemistry mock tomorrow, I’ll let you know what I get!

[@varoom4579]

how’d it go?

[@sp1r1t59]

what did u gettt??????

[@zahralovespopcorn]

sir what's your fav science to teach?

[@Freesciencelessons]

Biology is my favourite Science but I actually prefer teaching Chemistry. Students can be really good at Chemistry if they understand a relatively small number of concepts.

How come this video was remade

[@Freesciencelessons]

I'm remaking all of the videos that have the animated character in them. I'm also remaking all of the Chemistry 1 videos as the style was different to the rest (and I have much better sound equipment now). None of the content will change.
