Chemistry Formulas
amu = atomic mass unit&
= Avogadro Number = 6.023*10
--------------------------------------------------------
Percentage Composition
-- Na = 23 \ 23/69 = 33%.
N = 14 = 69 14/69 = 20%.
O
= 32 / 32/69 = 46%
Moles
g/amu = moles 33g/44 = .75 moles
Gram Molecular mass
amu's = gram molecular mass
C
C -- 12 + 12 = 24 \ 26grams)
H -- 1 + 1 = 2 /
Atoms Weight
# grams / N
Carbon -- 12g / N
= 1.99*100
Number of Molecules
moles * N
-- .32 moles * N
= 1.9*10
Simplest Formula
Boron 78.14% -- 78.14/11 = 7.1 -- 7.1/7.1 = 1G
Hydrogen 21.86% -- 21.86/1 = 21.86 -- 21.86/7.1 = 3 ans: B
Total # of Atoms Present
moles * N
* atoms present1
-- 1.25 moles * N
* 5 = 3.7643*10
Molar Volume
# of moles * 22.4
.8 moles * 22.4 = 17.93 liters
# of Molecules Present
moles * N
1.25 moles * N
= 7.5*10
Electron Configuration
Quantam Numbers
n = 1,2,3,4...
l = n - 1
m = 2l + 1
s = -(1/2) or +(1/2)
