|
natural % abundance?
|
isotopes naturally occur in fixed proportions in elements.
percent abundances of all isotopes in an element add up to 100%. So each element will consist of diff. numbers of isotopes of diff. % abundance. |
|
|
Atomic mass definition
|
the average mass of 1 atom of an element
this is obtained by averaging together the masses of each isotopes of that element, weighted by the % natural abundance. |
|
|
equation of atomic mass of an element
|
=(mass isotope 1)*(fractional abundance 1)*(mass isotope 2)*(fractional abundance)
**remember to make % abundance into fraction by dividing it into 100. |
|
|
building block in a ionic compound is called a ________
|
formula unit
formula units can aggregate and pack tightly to form a 3D crystal lattice |
|
|
definition of formula mass
|
formula mass is the mass (in amu) of:
1. an atom (for monatomic elements) 2. a molecule (for diatomic elements and covalent compounds) 3. a formula unit (for ionic compounds) |
|
|
formula mass is obtained by using ______ and _______
|
formulas and atomic masses (from the periodic table)
eg: Al = 26.98 amu eg: dinitrogen diflouride = N2F2 (14.02*2 + 19.00*2 = 66.02) |
|
|
mole quantities
|
need very large numbers of atoms/molecules/formula units of substances in order to have macroscopic quantities of substances
where 1 mole = 6.022 * 10^23 atoms/molecules/fu of that substance -- known as Avagadro's number |
|
|
mole quantities of substances have unique masses known as its MOLAR MASS. define molar mass.
|
(MM) is mass in GRAMS of 1 mole of a substance.
**the MM of a substance is identical to its formula mass, but the units are in GRAMS!!** |
|
|
compounds obey the law of ________ a.k.a. law of definite proportions
|
"law of constant composition
-that the proportions of elements by mass is fixed in a given compound. - usually reported as % by masses. |
