An automobile gasoline tank holds 50 kg of gasoline. When the gasoline burns, 175 kg of oxygen are consumed and carbon dioxide and water are produced. What is the total combined mass of carbon dioxide and water that is produced?

Answer 1

According to the law of conservation of mass, the number of starting products is equal to the number of finished products. At the entrance we have 50 kg of gasoline and 175 kg of oxygen, in total they give 50 + 175 = 225 kg. Then the formed water and carbon dioxide gas will give a total of 225 kg.
