A chemist reports a percentage yield of 0% for a reaction. Which is the most likely interpretation?
When calculating theoretical yield you must base the calculation on the limiting reagent. Which statement is correct?
Hydrogen + chlorine ? hydrogen chloride. Theoretical yield of HCl = 36.5 g; actual yield = 29.2 g. What is percentage yield (to 3 s.f.)?
The maximum theoretical mass of a salt is 12.5 g and the percentage yield is 92.8%. Calculate the actual mass of salt produced.
Which action would increase percentage yield of a crystallised salt product?
A student’s measured actual yield is higher than the theoretical yield calculated using balanced equation and pure reactants. Best explanation?
A student planned to make 0.250 mol of product but actually obtained 0.160 mol. What is percentage yield?
Which statement about reporting percentage yield is correct?
Which calculation gives percentage yield when given moles: theoretical moles = 0.250 mol and actual moles = 0.190 mol?
A reaction produces theoretical gaseous product volume 24.0 dm3 but measured collection is 19.2 dm3. What is percentage yield?
A student calculates percentage yield using the formula: percentage yield = (mass of product actually obtained / maximum theoretical mass of product) × 100.
