An automobile gasoline tank holds 23 kg of gasoline. When the gasoline burns, 86 kg of oxygen is consumed, and carbon dioxide and water are produced.

Question:

What is the total combined mass of carbon dioxide and water that is produced?

Answer:

109 kg

Explanation:

When 23 kg of gasoline burns by consuming 86 kg oxygen, they produce carbon dioxide and water. To find the total combined mass of carbon dioxide and water, we will use mass conversation law.

According to mass conversation law, the mass of the product is equal to the mass of reagent.

Mass of reagent = Mass of product

In this reaction,

Gasoline + O2 → CO2 + H2O

23 kg + 86 kg →?

23 kg + 86 kg = 109 kg

Combined mass of carbon dioxide and water will be 109 kg.
