Mol% or weight%? Weight percent seems more likely; let's assume that and see what we come up with. We'll assume 100g of the substance to make the numbers pretty; in that case we have: * 34.9 g Na / 23.0 g/mol Na = 1.52 mol Na * 16.4 g B / 10.8 g/mol B = 1.52 mol B (so far the weight percent is looking like a good assumption) * 48.6 g O / 16.0 g/mol O = 3.04 mol O (looking like a greatassumption) Converting that to small whole number ratios, we get an Na:B:O ratio of 1:1:2, so the empirical formula is NaBO2.

What is the empirical formula of a compound that is 4 percent sulfur and 6 percent oxygen by weight?
We can't tell. What's the other 90 percent? If you meant 40/60 instead... the mass of sulfur is twice that of oxygen, so a mass ratio of 40:60 is equivalent to an atom ratio of 1:3. The empirical formula would be SO3.
