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.
