Compare the system (still at 50 °C) with a volume of 1.0 L and with 3.0 L. What is the total amount of gas (mol) present in the container at each of these volumes?

The total amount of gas present in the container of 1 L is 0.0446 moles and in container of 3 L is 0.1334 moles.

Explanation:

It is known that 1 mole of any gaseous element contains 22.4 litres of that gas molecules. So in order to determine the total amount of gas present in 1 L and 3 L, we can divide the given volume with the reciprocal of 22.4 litre to determine the moles of gas at 1 L and 3 L respectively.

So for 1 L

So no. of moles in 1 L = 0.0446 moles of that gas is present in 1 L volume.

Similarly, total amount of gas present in 3 L is

No. of moles present in 3 L =

So, the total amount of gas present in 1 L is 0.0446 moles and in 3 L is 0.1334 moles. Thus, it can be stated that the number of moles increases with increase in the volume or on expansion of gas molecules.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
