The conclusion which can be drawn from the results that more ice added caused a greater change in temperature.
<h3>Why temperature of substance changes?</h3>
Temperature of any substance will change if some amount of energy is absorbed or released by that substance in the form of heat.
If in simple water, we add some amount of ice then energy or heat from the whole mixture will released as a result of which temperature of the water decreases. And decrease in temperature will depend on the amount of added ice.
Hence, more ice added caused a greater change in temperature.

V1/T1=V2/T2
524 cm^3/491 K =V2/297K
V2=(524 cm^3*297K)/491 K= 317K
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We do as follows:
10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
