The following is the arrangement of the given molecules in decreasing order of mass:
<u>Solution:</u>
First inorder to arrange the elements in descending order of their mass we have to calculate the molecular mass of each element. The calculation is as follows:
<u>Mass of C6H14:</u>
<em>Mass of C6H14 is 86.172</em>
<u>Mass of NO2:</u>
<em>Mass of NO2 is 46.0055</em>
<u>Mass of Fe2O3:</u>
<em>Mass of Fe2O3 is 159.6882</em>
<u>Mass of CaCO:</u>
<em>Mass of CaCO will be 68.0874</em>
So, the order will be which is
