When limestone rock, which is principally calcium carbonate, is heated, a reaction occurs. If 11.7 g of carbon dioxide were produced in the lab from the decomposition of 30.7g of calcium carbonate, what is the percent yield for the reaction?

86.7 %

Explanation:

To calculate the moles, we use the equation:

a) moles of

According to stoichiometry :

1 moles of give = 1 mole of

Thus 0.307 moles give = of

Mass of

Therefore, the percent yield for the reaction is, 86.7%
