#"molar mass" = "2 × g Fe + 3 × g O" = " g Fe + g O" = " g Fe"_2"O"_3# This tells us that there are g #"Fe"# in g #"Fe"_2"O"_3# . Step 2.
mass of one formula unit, that is, one iron, three nitrogens and nine oxygens. All three terms are often used interchangeably, although molar mass is technically the only one that is in units of grams/mole.
the empirical mass of barium phosphate (Ba3(PO4)2) is g/mol. To find the molar mass, you would need to balance the formula this compound is in. If there is no coefficient in front of this chemical formula once it has been balanced, the molar mass of barium phosphate is g/mol as well.
