The mystery fuel speedster! (Homework ) For fun, you build an explosive car with your little brother by attaching wheels to an empty windshield washer container. To advance it, you add 1.20 ml (  = 0.7915 g/ml) of a liquid but volatile fuel into the container. You close the cap and shake to evaporate the liquid. Finally, you place the car on its wheels, remove the cap and insert a burning wooden rod into the container. A flame suddenly comes out of the car, which is propelled with good speed in front of your little brother surprised, but all upset by the maneuver.   The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol.   During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too. The volume of the windshield washer container used is 4.00 litres. Useful Info: There is 21.0% gaseous oxygen in the air and initial conditions are T = 25.0°C and P = 100.0 kPa. In small quantities, the fuel occupies a negligible pressure in the container.   A) First, determine the empirical formula, then the molecular formula for the unknown fuel. B) Then write down the balanced equation of this combustion. C) Finally, using the data provided, calculate the mass of carbon dioxide that is produced by this reaction.

The volatile fuel is composed of 37.5% carbon, 12.6% hydrogen and 49.9% oxygen. Its molar mass is approximately 32.0 g/mol.

During the reaction, the fuel (gaseous) burns in the presence of gaseous oxygen, and the products of the reaction are carbon dioxide and water, gaseous too.

• A) First, determine the empirical formula, then the molecular formula for the unknown fuel.
• B) Then write down the balanced equation of this combustion.
• C) Finally, using the data provided, calculate the mass of carbon dioxide that is produced by this reaction.
