Question

Gaseous C2H4 reacts with O2 according to the following equation:

Answer 1

Answer:

Each mole of gas occupies 22.4 L at STP.

Liters of gas = 17.25 x 22.4

= 3.86 x 10² L

Your correct answer is C 3.86 x 10^2 L

Explanation:

Answer 2

Each mole of C₂H₄ requires 3 moles of O₂ to react.

5.75 moles of C₂H₄ will require:
3 x 5.75 = 17.25 moles

Each mole of gas occupies 22.4 L at STP.
Liters of gas = 17.25 x 22.4
= 3.86 x 10² L

The answer is C.
