Ili kubainisha fomula ya empiriki, tutafuata hatua hizi: Step 1: Badilisha asilimia kuwa gramu kwa kudhani tuna sampuli ya 100 g. • Carbon (C): 64.9 g • Hydrogen (H): 13.5 g • Oxygen (O): 21.6 g Step 2: Badilisha gramu kuwa mol kwa kutumia masi za atomiki zilizopewa (C = 12.0, H = 1.0, O = 16.0). • Moli za C: 64.9 g12.0 g/mol = 5.408 mol • Moli za H: 13.5 g1.0 g/mol = 13.5 mol • Moli za O: 21.6 g16.0 g/mol = 1.35 mol Step 3: Gawanya idadi ya moli kwa idadi ndogo zaidi ya moli ili kupata uwiano rahisi. Idadi ndogo zaidi ya moli ni 1.35 mol (ya Oksijeni). • Uwiano wa C: (5.408)/(1.35) ≈ 4 • Uwiano wa H: (13.5)/(1.35) = 10 • Uwiano wa O: (1.35)/(1.35) = 1 Step 4: Uwiano wa moli ni namba kamili, kwa hivyo fomula ya empiriki ni C_4H_10O. Fomula ya empiriki ya alkanol ni: C_4H_10O 3 done, 2 left today. You're making progress.
