Arrange these molecules in order of decreasing mass: C​6​H​14​ , NO​2​ , Fe​2​O​3 ​, and CaCO​
babunello [35]

The following is the arrangement of the given molecules in decreasing order of mass: \text{ Fe2O3} > \text{C6H14} > \text{CaCO} > \text{NO2}

<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>

C\rightarrow6\times12.01 = 72.06

H\rightarrow14\times1.008 = 14.112

<em>Mass of C6H14 is 86.172</em>

<u>Mass of NO2:</u>

N\rightarrow1\times14.0067 = 14.0067

O\rightarrow2\times15.9994 = 31.9988

<em>Mass of NO2 is 46.0055</em>

<u>Mass of Fe​2​O3:</u>

Fe\rightarrow2\times55.845 = 111.69

O\rightarrow3\times15.9994 = 47.9982

<em>Mass of Fe2O3 is 159.6882</em>

<u>Mass of CaCO:</u>

Ca\rightarrow1\times40.078 = 40.078

C\rightarrow1\times12.01 = 12.01

O\rightarrow1\times15.9994 = 15.9994

<em>Mass of CaCO will be 68.0874</em>

So, the order will be 159.6882>86.172>68.0874>46.0055 which is \text{ Fe2O3} > \text{C6H14} > \text{CaCO} > \text{NO2}
