7.0 mol Mn reacts with 5.0 mol
O2 according to the equation below:
2Mn + O₂ → 2MnO
How many moles of MnO form from
5.0 mol Mn?
[?] mol MnO
Round your answer to the tenths place.

Answer 1

5 moles of MnO form from 5.0 mol Mn. Details about stoichiometry can be found below.

How to calculate number of moles?

The number of moles of a substance can be calculated stoichiometrically as follows:

According to this question, the following chemical equation is given as follows:

2Mn + O₂ → 2MnO

2 moles of Mn forms 2 moles of MnO

Hence, 5 moles of Mn will form 5 × 2/2 = 5 moles of MnO.

Therefore, 5 moles of MnO form from 5.0 mol Mn.
