calculate the number of atoms of na in 4.00 moles
|
4.oo moles na
6.022 x10^23 ------------------- = 2.41x10^atoms of na 1 moles |
|
the unit on top
|
should go on the unit on the bottom
|
|
5 terms that are the same
and u give your answer in grams they will be the same numerically |
molecular mass
formula mass formula mass molecular weight molar mass |
|
molar mass=
|
the atomic mass,molecular mass of formula mass measured in grams
|
|
formula mass
|
ex- h2o
h 2x1.01g= 2.o2 o 1x16.oo g 18.02 |
|
formula mass is
|
the atomic masses of the atoms in the element times thier subscript
so answer equals grams per mole of the element |
|
ex
moles in 50.00 of glucose(c6h12o6) |
50g of c6h12o60
------------------------------ 180.18 gc6h12o6 end up dividing 50 by 180.18 = 0.27moles of c6h12o6 |
|
grams to moles
|
use the molar mass = to formula mass
|
|
finding percent of a part of an atom
|
figure out molar mass
part divided by molar mass x 100 ex 72.06 ----------- x100=39.00 180.10 when you get ratios cross mulitply and divide 39.99 8.95 _____=______ 100g 224g |
