What is the mass of 0.7891 mol of ferric oxide (fe, o3)? a. 12.60 g b. 126.012 g c. 0.0126 g d. 159.692 g e. 1.26 g

THIS IS THE BEST ANSWER 👇

The answer to your question is letter B.

Explanation:

Process

1.- Calculate the molecular mass of Ferric oxide

Fe = 56g x 2 = 112 g

O = 16 x 3 = 48 g

Mass = 112 + 48 = 160 g

2.- Calculate the mass of 0.7891 moles of Ferric oxide

160 g of Fe₂O₃ 1 mol

x 0.7891 mol

x = (160 x 0.7891) / 1

x = 126.2 g
