Explanation:

In order to calculate the number of moles of a compound, we will find it out as follows.

No. of moles of chromium(III) chloride = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{158.36}$

= 0.63 moles

No. of moles of $NH_{3}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{17}$

= 5.88 moles

No. of moles of $MgCl_{2}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{95}$

= 1.05 moles

No. of moles of $H_{3}PO_{4}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{98}$

= 1.02 moles

No. of moles of KCl = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{74.5}$

= 1.34 moles

No. of moles of $N_{2}O_{3}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{76}$

= 1.31 moles

No. of moles of $CH_{4}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{16}$

= 6.25 moles

No. of moles of $C_{3}H_{8}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{44}$

= 2.27 moles

No. of moles of $LiClO_{3}$ = $\frac{mass}{\text{molar mass}}$

= $\frac{100}{90.39}$

= 1.11 moles

Therefore, we can conclude that out of the given options $CH_{4}$ contains the largest number of moles of compound.
