The simplest formula is CโHโ .
Explanation:
The moles of COโ are the moles of Carbon because oxygen is in excess. Thus, the double of moles of HโO are the moles oh hydrogen (Double because HโO has two hydrogens for each mole).
4,822g COโ ร (1mol / 44,01 g) = 0,1096 moles of C
1,650g HโO ร (1mol / 18,01 g) ร 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 ร 3 = 3 Carbon
1,672 ร 3 = 5 hydrogen
Thus, the simplest formula is CโHโ .
