Cello · Answer 1

The number of moles of O2 that are needed to react with 24 moles of C2H6 is 84 moles of O2

Explanation

Step 1: write the equation for reaction

= 2C2H6 + 7O2 → 4CO2 + 6H2O

Step 2: use the mole ratio to determine the moles of O2

that is the mole ratio of C2H6 : O2 is 2:7 therefore the moles of O2 = 24 x7/2 = 84 moles of O2
