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.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
