Question

when you combust 100.0 g 100.0 g of propane at 500. k 500. k and 1.00 atm 1.00 atm in a closed container, you expected to collect 279 l 279 l of carbon dioxide. instead, when you collect the gas, it measures 651 l 651 l in total. which of the following accounts for this difference?

Answer 1

for the following accounts Theoretical yield was calculated incorrectly

The random error that results from measuring the masses of the reactants and the product (+ or - 0.001 g?) could cause experimental error in a yield measurement. Or it can be a deliberate mistake brought on by impurities that are still in the final product (and artificially inflating its mass). Because the real yield is frequently lower than the theoretical value, percent yield is typically lower than 100%. This may be due to incomplete or conflicting reactions or sample loss during recovery.
