Answer:
The yield is 16 moles of CO2 per 2 moles of isooctane.
The mass of CO2 is 1.15 billion tonnes
Explanation:
First we set the unbalanced equation:
Now we proceed to balance the equation:
With the equation balanced, we see that the theoretical yield is 16 moles of CO2 per 2 moles of isooctane and we can proceed to make calculations with the following data:
Knowing the different relations between mass, density and molar mass, we have the following results:
<u>Answer:</u> The correct answer is Option D.
<u>Explanation:</u>
To calculate the moles of a solute, we use the equation:
We are given:
Volume of sulfuric acid = 450mL = 0.45 L (Conversion factor: 1 L = 1000 mL)
Molarity of the solution = 0.5 moles/ L
Putting values in above equation, we get:
For the given chemical reaction:
By Stoichiometry of the reaction:
1 mole of sulfuric acid reacts with 2 moles of sodium bicarbonate.
So, 0.225 moles of sulfuric acid will react with = of sodium bicarbonate
To calculate the mass of sodium bicarbonate, we use the equation:
Moles of sodium bicarbonate = 0.45 moles
Molar mass of sodium bicarbonate = 84.007 g/mol
Putting values in above equation, we get:
Hence, the correct answer is Option D.
