Propenoic acid, C3H4O2, is a reactive organic liquid that is used in the manufacturing of plastics, coatings, and adhesives. An unlabeled container is thought to contain this liquid. A 0.257-g sample is combusted to produce 0.180 g of water and 0.291 g of carbon dioxide.

Expert Solution

Step 1

Combustion :-

Burning of a compound in excess of air or oxygen is called combustion.

Combustion of any hydrocarbon will produce carbon dioxide and water.

The percentage of carbon in the compound can be calculated by using the formula

$% C = \frac{12}{44} \times \frac{W_{C O_{2}}}{W_{c o m p o u n d}} \times 100$

Similarly percentage of hydrogen is calculated by

$% H = \frac{2}{18} \times \frac{W_{H_{2} O}}{W_{c o m p o u n d}} \times 100$
