Like i said how do i figure kg of cobalt in 3.463 kg Co₂O₃ cobalt (III) oxide

[EpicWinston]

3.463 kg Co2O3 cobalt (III) oxide to grams = 3463 grams

grams Co2O3 cobalt (III) oxide into moles Co2O3 cobalt (III) oxide = 20.86 moles Co2O3
3463 grams Co2O3 * 1 mol/ 166 g Co2O3

moles Co2O3 cobalt (III) oxide to moles Co = 41.7 moles Co
20.86*2 Moles Co/ 1 mole Co2O3

Moles of Co to g Co = 2461.65
41.7mol Co*59 g/ 1 mol

g Co to kg Co = 2.46165
