Question

7.0 mol Mn reacts with 5.0 mol

O2 according to the equation below:
2Mn+0₂ → 2MnO

How many moles of MnO form from7.0 mol Mn?

[?] mol MnO

Round your answer to the tenths place.

Answer 1

The answer that I got was 7.0.

Step-by-step explanation:

It said round to the tenths place so put the .0 after the seven and see if that helps.

Answer 2

= 7 moles Mno

Step-by-step explanation:

We have been asked to determine the number of moles required to form MnO.

Mole ratio

Mn : MnO = 1 : 1

The reaction ratio therefore is 1 : 1

Thus 7 moles of Mn react to form 7 moles MnO since we have similar ratio.
