Question

An automobile gasoline tank holds 21 kg of gasoline. When
the gasoline burns, 84 kg of oxygen is consumed and carbon
dioxide and water are produced. What total combined mass of
carbon dioxide and water is produced?

Answer 1

Answer:

105 kilograms If it's helpful please mark as brainlist

Answer 2

Hence, The combined mass of carbon dioxide and oxygen is 105 Kg

GIVEN

Volume of gasoline tank = 21 kg

Amount of oxygen required = 84 kg

TO FIND

The combined mass of carbon and water produced.

SOLUTION

We can simply solve the above problem as follows;

It is given,

To burn 21 kg of gasoline, 84 kg of oxygen gas is consumed and carbon dioxide and water is produced.

We can represent the above scenario as a chemical equation;

Gasoline + Oxygen = Carbon dioxide + water

21 kg 84 kg

According to law of conservation of mass the mass of an isolated system is neither created nor destroyed. It can also be stated as the mass of reactant is equal to mass of the product formed in a chemical reaction.

So,

Combined mass of Reactant = Combined mass of Product.

21 + 84kg = 105 kg = combined mass of carbon dioxide and reactant.

Hence, The combined mass of carbon dioxide and oxygen is 105 Kg
