What is the empirical formula for 63.5g silver, 8.2g nitrogen, 28.3g oxygen

Explanation:

When calculating an empirical formula from grams, divide each mass by their molar mass to convert your grams to moles.

63.5/107.7 = 0.5896 mol

8.2/14.01 = 0.5852mol

28.3/15.99 = 1.770 mol

Then you will divide all of your mol values by the SMALLEST number of moles. This gives you whole numbers that are the mole ratio (subscripts) of the empirical formula.

0.5896 mol/0.582 mol= 1

0.5852mole /0.582 mol= 1

1.770mol/0.582 mol= 3

So the empirical formula is

stupid i wont let you get a chance
