Ron weasley isn't the best experimentalist. after an experiment he ends up with only 3.10 g of product. however, the same reacti
1 answer:
The experiment should theoretically yield 3.50 g of the product.
However during the experiment it can yield only 3.10 g of the product.
actual yield is lesser than the theoretical yield, therefore we need to find the percentage yield.
Percentage yield can be calculated using the following equation
Percent yield = 3.10 g / 3.50 g x 100% = 88.6%
However during the experiment it can yield only 3.10 g of the product.
actual yield is lesser than the theoretical yield, therefore we need to find the percentage yield.
Percentage yield can be calculated using the following equation
Percent yield = 3.10 g / 3.50 g x 100% = 88.6%

Answer : 0.0392 grams of Zn metal would be required to completely reduced the vanadium.
Explanation :
Let us rewrite the given equations again.
On adding above equations, we get the following combined equation.
We have 12.1 mL of 0.033 M solution of VO₂⁺.
Let us find the moles of VO₂⁺ from this information.
From the combined equation, we can see that the mole ratio of VO₂⁺ to Zn is 2:3.
Let us use this as a conversion factor to find the moles of Zn.
Let us convert the moles of Zn to grams of Zn using molar mass of Zn.
Molar mass of Zn is 65.38 g/mol.
We need 0.0392 grams of Zn metal to completely reduce vanadium.
