The Mole Concept
Mole = 6,02
Lp
Avogadio's Number
No of particles latoms lions no. moles
* mass = no. moles mass of mole of element
no. moles = mass of Sample
MaSS of Imole of element
Mole The ST unit for the amount of sulostance
Molar mass the mole
Molar mass: The mass in
grams of one mole of tat Substance
Unit =
9.mol™
Calculating hydvate
M(Na2C03. 10H20) = 2(23) +12+3(16) +10(2+16)
46+ 12 +48 + 10(18)
, Basic calculations involving the mole
amount(mol) - mass (q
Calculating No. of molecules
number of molecules formula units = no. moles x NA
LD 6,02 X 102
Calculating no of tonsjatoms in a molecule
0 Calculate no. of moles
2 Determin e no. of atoms (chemical formula)
no. of moles
by no of atoms
Calculate no of atoms of element in compound
O Muthply no of moles
of element by NA
