Chapter10 Flashcards
RP
Atoms,molecules, formula units, etc
Molar mass
The mass of one mole of an element (g/mol)
Mol
6.02x10^23 RPs of a substance
Avagaradro’s number
The # of RPs in a mol, 6.02x10^23
Standard Temperature and Pressure
0*C 1 atm (atmosphere)
Molar volume
22.42, the molar volume of a gas at STP
Percent Composition
The relative amt of the elements in a compound
Empirical Formula
Gives the lowest whole number ratio of the atoms of the elements in a compound
Molecular formula
A chemical formula of a molecular compound that shows the kinds and number of atoms present in a molecule
Unit for mass
g
Unit for volume
L
Molar mass (how to calculate)
Suk of the atomic mass(es)
g to mols
And vice versa
Mass/1 x 1mol/molar mass
RP to mols
And vice versa
RP/1 x 1mol/6.02x10^23
Volume to mols
And vice versa
V/1 x 1mol/22.4L
