GCSE Chemistry - How to Calculate Concentration in grams per decimetre cubed #30

How to calculate concentration in g/dm³.

To measure how much of a particular substance we have a give volume, we can work out the concentration. In this video we cover how to calculate concentration in grams per decimetre cubed, and have a go at some examples.

This video is suitable for:
- Higher and Foundation tiers
- All exam boards
- Triple and combined science

The most concise and understandable way of teaching GCSE courses. Fab work Cognito!!! You really do put competition with freesciencelessons :)

thanks for this man, I have my last ever GCSE chemisty exam tomorrow.

you are saving me right now, i have had this explained to me like 10 times and i now understand in prep for my chemistry mock tomorrow thank you

Great video!! Another great thing to know is: A Mole is also = Concentration x Vol, where Concentration can be written as mol/dm³. This can then be converted to grams by multiplying moles by Mr.

Can you guys start doing A-Level science too!!!!

I am sure everyone who watch this video will understand the topic

When did we stop using Liters for liquid volume? We used liters in high school, what happened between when I graduated high school and now? I'm not old yet, I just graduated university and came out to have fun. Never seen decimeters before used in the lab.

Is this formula different from the moles concentration and volume formula

If you ever want to succeed in Physics or Chemistry or even Biology: Remember, do step by step, even if your last answer is wrong you still get bonus marks, check units, they always cost you marks due to conversions or not writing them in exam.
