How many Aluminum atoms are in 549.371 grams of Al2O3? Answer in units of atoms.If someone could please give the steps in order to solve this along with the numerical answer (NOT rounded to significant digits) it would help me greatly, as I have no calculator.
Get the Molar mass of the compound Al (2 ) (26.98 ) 53.96 g/mol ( 2 is the subscript in the formula,its number of atom in that one formula unit, 26.98 grams/ mol is atomic mass taken from the periodic table ) O (3) ( 16) 48 g/mol ( 3 in the number of oxygen atoms in the formula unit, 16 is the atomic mass taken from the periodic tablemultiply it to get 48 ) 53.96 + 48 101 g/mol this is the molar mass of the compound whew the above answer is correctBernie.
