Combustion analysis of toluene, a common organic solvent, gives 4.69 mg of co2 and 1.10 mg of h2o. if the compound contains only
BartSMP [9]
CₓHₐ + (x+a/4)O₂ = xCO₂ + a/2H₂O

n(CO₂)=4.69 mg/44.01 mg/mmol = 0.1066 mmol

n(H₂O)=1.10 mg/18.02 mg/mmol = 0.06104 mmol

C : H = 0.1066 : 0.06104*2 = 0.1066 : 0.12208 = 1 : 1.1453 = 7 : 8

C₇H₈ + 9O₂ = 7CO₂ + 4H₂O

C₇H₈
