Calculate the mass of 12.04 per 10 ^ 23 iron oxide molecules.

In this case, according to Avogadro’s law, 1 mol of iron oxide contains 6.02 x 10 ^ 23 (degrees) Then, according to the condition of the problem, we get 12.04 x 10 ^ 23: 6.02 X 10 ^ 23 = 2 (mol)

And this will be in the scales. But first, let’s calculate the molecular weight of iron oxide. m (Fe2O3) = 56 x 2 + 16 x 3 = 160 (g / mol)

Well, 2 moles of this substance will be equal.

160 (g / mol) x 2 mol = 320 (grams)
