what is the molar volume?
22.4 L at STP (standard temperature and pressure) [gas only]
at the same pressure and temperature, equal volumes of all gases contain the same number of molecules
avagadro's law
percent composition formula
percent by mass (element) = (mass of element/mass of compound) x 100
the number of carbon atoms in exactly 12 grams of pure carbon-12. this is 6.02x(10^23)
avogadro's number
SI base unit to measure the amount
mol (abbreviated)
mole formula
# of moles = grams/molecular mass
composed of hydrogen(s) + anion that ends in -ite
(root)-ous acid
composed of hydrogen(s) + anion that ends in -ate
(root)-ic acid
composed of hydrogen(s) + anion that ends in -ide
hydro-(root)-ic acid
when added to water, hydrogen(s) are released to form what?
hydronium ions in aqueous solution
covalently bonded molecular compound that contains one or more hydrogen(s) that can form ions (cations)
acid
two element, non-ionic compounds that ends in "-ide." prefixes are used to indicate the number of each elements atoms in a molecule
binary molecular compounds
a molecule consisting of only 2 atoms which are covalently bonded together - there can be single, double or triple bonds
diatomic molecule
