WebAug 25, 2024 · Example 4: To Determine Molecular Formula from Mass Percentages. It is known that a chemical compound contains 52.14 % carbon, 13.13 % hydrogen, and 34.73 % oxygen. The molar mass of the chemical is also known; it is 46.069 g mol −1. Step 1: First, we need to convert the mass percentages into moles. WebHere is the systematic algebraic way to do it: First expand the LHS: 2x³ - 14x² + 20x = 8 Subtract 8: 2x³ - 14x² + 20x - 8 = 0 We solve this equation by factoring it. From our …
