Answer: 95%
Explanation:
We first write down the balanced reaction equation as shown in the image attached. Next we identify the limiting reactant from the given data. Oxygen is the limiting reactant in this case and it is the mass of oxygen reacted that is used in the estimation of the theoretical yield as shown in the image attached. The percentage yield is then calculated according to the formula shown in the image attachment.
The neutralization reaction between potassium hydroxide and sulfuric acid is as follows
2KOH + H2SO4 ---> K2SO4 + 2H2O
number of moles of KOH= (43.74 x 0.500)/ 1000= 0.02187 moles
the reacting ratio of KOH to H2SO4 is 2:1 therefore the moles of H2SO4 is = 0.021187/2= 0.01094 moles
concentration(molarity) = ( 0.01094/50 ) x 1000= 0.2188M
