(a) the characteristic odor of pineapple is due to ethyl butyrate, a compound containing carbon, hydrogen, and oxygen. combustio
ella [17]

By stoichiometry and assume that:

CxH2xOy + zO2 -> xCO2 + xH2O 

<span>
CO2: 9.48/44 = 0.215 mmol 
H2O: 3.87/18 = 0.215 mmol 
mass of C = 0.215 * 12 = 2.58 mg 
mass of H = 0.215 * 2 * 1 = 0.43 mg 
mass of O in ethylbutyrate = 4.17 - 2.58 - 0.43 = 1.11 mg 
So C/O = 2.58/1.11 ≈ 3 </span>

<span>
Thus we have C3H6O</span>

This means that the bonding (and non-bonding) electrons will repel each other as far away as geometrically possible.
