need to know if all the formulas are right, friggin got like 25% on my last test lol >_>

mass to moles - mass given / atomic mass
moles to mass - mole given x atomic mass

particles to moles - given particles / (6.02x10^23)
moles to particles - (6.02x10^23)(given moles)

moles to number of atoms - mole given x (6.02x10^23) x atoms in molecule
number of atoms to moles - (mole given x atoms in molecule) / (6.02x10^23)

volume of gas to moles - given volume / 22.4
moles to volume of gas - given mole x 22.4

unless you in higher chem or phy classes..

the formulas will be provided for you unless you got a strict instructor

beside if you already in a higher class.. you probably know the formulas already.. if not.. then.. study hard :??

good luck with your test..

im in 1st year chem honors, the formulas aren't totally provided for us >_>

Ahahaha, I remember when we got this crazy teacher dude in high school phy class, he let us open any book, use any calculator, any shit that we can use for the test ...

And yet, the whole class average is like 25% OUT OF 100, even the best student is like 40, me, I think 15, but that teacher dude said, anything below 20 is compensation for the ink that we use in the test ...

But again, he only lasts for one semester, LOL ...
