Percentage uncertainty and percentage yield Flashcards
1
Q
How do you calculate percentage uncertainty?
A
Percentage uncertainty = (Number of readings x Uncertainty on equipment / Quantity measured) x 100
2
Q
How do you calculate percentage yield?
A
% yield = (actual yield / theoretical yield) / 100
3
Q
What are some reasons for the percentage yield to be less than expected?
A
Incomplete reactions
Side products produced
Reversible reactions
Impure reactants
Practical losses during an experiment
