In a combustion reaction, 30g of propane burns in air to produce 70g of carbon dioxide.calculate the percent yield of carbon dioxide?
1 Answer
Explanation:
balanced reaction:
the relative formula mass of
the mass of propane burnt is
number of moles = mass / molar mass
the number of moles of propane burnt is approximately
the reaction forms
this means that theoretically,
the relative formula mass of
using the same equation mass = number of moles * molar mass, the theoretical mass of
we are given that the actual mass of
the percentage yield is calculated by dividing the actual mass of a product formed by the theoretical mass formed, and multiplying that ratio by
here, the percentage yield is
which is
