Yay, metric units, finally!
Congratulations on the grandchild!
thank you so much, if you please may you clarify in more details in next videos how to calculate the number of atoms in copper using just a ruler, thank you in advance
Google "mol" (chemistry). You don't use ruler to calculate number of atoms in copper. You get it's weigh and use it's "mol" weight, to actually get amount of atoms.
It would be nice if they would actually clarify what they've meant when they was talking about the ruler.
@@Soulskinner so did she mean to find volume and then get its mass from density formula and then convert that to g/mol ?
Thank you so much. Please how about lectures of organic synthesis? Is it available?
On quick search, there didn't seem to be any videos? (There might be... we just don't have time to do a deep search). There are some written materials available: ocw.mit.edu/search/ocwsearch.htm?q=organic%20synthesis. Best wishes on your studies!
@@mitocw thank you
@@mitocw terimakasih banyak
Measure area??? At the very least you need volume to estimate number of atoms. But easiest would be simply to weigh the sample. This is a poor example for aspiring scientists
neglected the thickness.
So,easy 😄
Cool
I am a genius.
Hi
my brother sent me this.😊
fyi the message in the intro cannot be decrypted because leading zeros aren't allowed in python
👍👍👍👍👍👍👍👍👍👍👍
This is funny.. you use ruler, but say ml instead of mm. And then you say it is estimate of atoms, while not counting the Z axis at all.
If you look at the pdf for the goodie bag it tells us the thickness is 0.005 inches and density for copper is 8.94 g/cm^3. Then you need to convert the inches to cm and use the periodic table for molar mass of copper. With a little math you get an answer.
From hydrogen gas u get compound which is fuel
Convert the fuel to a liquid and u get gas which can be recycled to its origen
why so serious?
why are YOU so serious when she snaps on her gloves?! :-0
I am confused by the "MIT GRANDPARENT" shirt. It is likely a QAnon message from MIT telling us that they are helping Trump (grandparent) save the world. This possibility is comforting.
