Thread: Converting Moles to Atoms, ect. (HS)

Stoiciometry Qs:

Ho do you

convert a certain mole of a molecule into atoms?
convert molecules to moles?
moles to molecules?
masses to liquid amounts in liters at stp?
convert atoms to moles?
masses to moles?
moles to liquid measures?
A bit clueless, I am.

If you want me to post these separately, OK.

Moliemoliemoliemoliemoliemolie....

1mol=6.02*10^23 atoms

i mol=22.4liters
and you can't go from mass to liters
unless it's an element and you use the periodic table!

No. of Molecules = No. of Moles * Avagadro Number
No. of Atoms = No. of atoms in a molecule * No. of Molecules ( from previous step)
Volume = Mass/ Density
Mass / Molecular weight = No. of Moles (Be sure to use the same units.)

Waah, just failed the quiz today with a 60. I'm going to need a LOT more help.

Hmmm... It would be easier if you could post the questions you got wrong or other specific questions.

Don't worry about the quiz, you will get better grades if you work on this.
