Question

4 Na + O2 → 2 Na2O

6.79 moles of O2 will react to form how many moles of Na2O?

Answer 1

13.94moles of Na₂O

Step-by-step explanation:

The balanced reaction expression is given as:

4Na + O₂ → 2Na₂O

Given parameters:

Number of moles of O₂ = 6.97moles

Unknown:

Number of moles of Na₂O

Solution:

To solve this problem;

1 mole of O₂ will produce 2 moles of Na₂O ;

6.97 moles of O₂ will produce 6.97 x 2 = 13.94moles of Na₂O
