density=

mass/volume

mass=

density x volume

volume=

mass/density

1 mole=

6.02x10^23

6.02 x 10^23

Avogadro's number

ionic

lowest ratio of cations to anions

molecular

exact ratio of the atoms of each element to the atoms of other elements present in teh molecule

percent composition

part/whole x 100

empirical formula

grams to moles,divide by least number of moles

molecular formula

find empirical formula(grms to moles, divide moles), find multiplier( molar mass of empirical formula/total molar mass)

solvent

more

solute

less

making solution more concentrated

less solvent or more solute

solution

homogeneous mixture

making solution more diluted

more solvent or less solute

Molarity

moles/liters

dilution equation

M1V1=M2V2

A+B=AB

synthesis

AB=A+B

decomposition

A+BC=AC+B

single displacement

AB+CD=CB+AD

double displacement

single displacement occurring

activity series

double displacement(precipitation) rules

solid(s) on product, only aqueous on reactant, new compounds on product
