General chemistry i (10418) (chem 1411) practice problems. A sample is analyzed as containing 24.09 grams of potassium, 0.308 moles of manganese, and 7.42 x 1023 atoms of oxygen. In the laboratory, a sample is found to contain 1.05 grams of nickel and 0.29 grams oxygen. 24.09 g k x (1 mol / 39.098 g) = 0.61614 mol /.308 = 2 0.308 mol mn = 0.308 mol /.308 = 1 Web determine the empirical formulas for compounds with the following percent compositions: 1 mol s 32.1 g s = 1.14 mol s fe 1.14s 1.14 fes 2.
