Answer:
The simplest formula is C₃H₅.
Explanation:
The moles of CO₂ are the moles of Carbon because oxygen is in excess. Thus, the double of moles of H₂O are the moles oh hydrogen (Double because H₂O has two hydrogens for each mole).
4,822g CO₂ × (1mol / 44,01 g) = 0,1096 moles of C
1,650g H₂O × (1mol / 18,01 g) × 2= 0,1832 moles of H
The next step is divide these numbers between the smaller one, thus:
0,1096 moles / 0,1096 moles = 1
0,1832 moles / 0,1096 moles = 1,672
The last step is to find a number to multiple that gives integers:
1 × 3 = 3 Carbon
1,672 × 3 = 5 hydrogen
Thus, the simplest formula is C₃H₅.
I hope it helps!
