Density of Body-Centred Cubic (BCC) - Potassium Example

[@AtlasMicha]

Amazing! I needed help in chem and I couldn’t figure it out but this vid helped so much!

[@dougshaw8119]

Thank you so much, I was stuck for 2 hours and you got me through it

[@lulamaemoully2009]

Did you forget to times the mass by number of atoms at 8:30?
Google says the density of solid crystalline potassium is 0.901g/cm3

[@levitheentity4000]

some sources even say it's 0.856
I'm tired, lol

[@winterfall9505]

amazing explanation

[@Stricknine47]

When finding the volume, why do you have to find the diagonal, rather than just cubing the edge lengths?

[@jasonmcgarry550]

I think I'ts because the diagonal has them all touching whereas they are not touching sideways. Not sure, just guessing from what I've seen

[@hillarymawira9390]

you've explainned it nicely...👍

[@sciencenerd7639]

wow, I didn't even know you could do that with the Pythagorean theorem

[@ryandolan2406]

I think you did your final volume wrong just a miss multiplication on the calculator it should be to the -7th right?

[@ryandolan2406]

Nevermind missed the cube

[@nickybutch3]

great work with this video

[@akazozo99]

Thank you so much.Now I totally understand it

[@pauljeffers6719]

Your formula for density (64r^3/3sqr3) is wrong because you have to rationalize the denominator. It should be (64x sqrt 3 x r^3)/9

[@chemistNATE]

Those are equivalent, but I understand that some teachers would want that.

Thanks
