Question

Determine the empirical formula of a compound containing 72 grams of carbon, 12 grams of hydrogen, and 96 grams of oxygen. Show your work or explain how you determined the formula by giving specific values used in calculations.

Answer 1

Answer:Obtain the mass of each element present in grams. Element % = mass in g = m.

Explanation:Generally speaking, in empirical formula problems, C = 12, H = 1, O = 16 and S ... 7) Use the scaling factor computed just above to determine the molecular formula: ... found to contain 64.80 % carbon, 13.62 % hydrogen, and 21.58 % oxygen by weight. ... 1) Percents to mass, based on assuming 100 g of compound present:.
