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
depth = side/lenght
the cube has all congruent sides
Volume = l³
Volume = 10³
Volume = 1000 cm³
A molecule has an empirical formula of ch, and its molar mass is known to be 26 g/mol and the molecular formula is C₂H₂ ethyne
Molecular formula of compound is (CH)n and the given molar mass is 26g/mol
Molar mass of (CH)n, C=12=n(12+1)=13n
So 13n and n=2
=13×2=26 and given molar mass is also 26g/mol
So here two carbon and two hydrogen so molecular formula is C₂H₂ and name is ethyne
