Answer:
54.66 liters
Step-by-step explanation:
First of all, remember this. 1 mole equals 22.4 liters.
Second of all, to show your work use dimensional analysis.
Write 2.44 moles and then put moles on the bottom and liters on top.
2.44 moles of O * 22.4 liters / 1 mol of O
Moles will cancel out.
2.44 x 22.4 = 54.656
Usually I would have used sig figs. But the question said to round your answer to two digits after the decimal point.
54.656 rounds to the hundreths place.
So 54.656 = 54.66
All in all, the final answer is 54.66 liters(don't forget the units).
Hope it helped!
