Answer:
Theoretical yield = 31.8 g
Explanation:
The formula for the calculation of moles is shown below:
For
Mass of = 60.0 g
Molar mass of = 101.96128 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given: For
Given mass = 30.0 g
Molar mass of = 12.0107 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
1 mole of aluminium oxide react with 3 moles of carbon
0.5885 mole of aluminium oxide react with moles of carbon
Moles of carbon = 1.7655 moles
Available moles of carbon = 2.4978 moles
Limiting reagent is the one which is present in small amount. Thus, aluminium oxide is limiting reagent.
The formation of the product is governed by the limiting reagent. So,
1 mole of aluminium oxide on reaction forms 2 moles of aluminium.
0.5885 mole of aluminium oxide on reaction forms moles of aluminium.
Moles of aluminium = 1.177 moles
Molar mass of aluminium = 26.981539 g/mol
Mass of sodium sulfate = Moles × Molar mass = 1.177 × 26.981539 g = 31.8 g
<u> Theoretical yield = 31.8 g</u>
