ANSWER: A
EXPLANATION:
THE FORMULA FOR DENSITY IS MASS DIVIDED BY VOLUME.
D= M/V
So divide the mass by the volume.
For A, 122 divided by 10.5 is 11.62
For B, 132 divided by 14.2 is 9.295
For C, 115 divided by 16.1 is 7.143
For D, 126 divided by 12.7 is 9.921
A IS THE ANSWER BECAUSE ITS THE LARGEST AMOUNG THE OTHERS.
E. Carbon dioxide isn't a product, it's taken in by the plant, oxygen is a product.
The number of moles of iron produced can be obtained by the use of stoichiometry.
<h3>What is stoichiometry?</h3>
The term stoichiometry has to do with mass - mole or mass - volume relationships. Stoichiometric relationships could be used to determine the amount of substance.
Now the reaction equation as well as other details are not shown in this question hence a numerical anwer can not be provided. As such, we can know that the balanced reaction equation can always be used to obtain the amount of iron by stoichiometry.
