Answer:

Explanation:
Hello there!
In this case, since this imaginary gas can be modelled as an ideal gas, we can write:

Which can be written in terms of density and molar mass as shown below:

Thus, by computing the pressure in atmospheres, the resulting density would be:

Question:
What is the total combined mass of carbon dioxide and water that is produced?
Answer:
<u><em>109 kg</em></u>
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.
