Explanation:

To solve this question, we need to use the following formula:

M = n/V

So:

M = ??

n = 2.634 mol

V = 25.2 L

M = 2.634/25.2

M = 0.105 mol/L

Answer: a. 0.105

aniked [119]

You have to use the molar volume of gas which is 22.4L/mol at STP. To find the number of moles of from a given volume of gas at STP, you need to divide the given volume by 22.4L/mol.
44.4L/22.4L/mol=1.98mol of gas

The labeled diagram is given in the image attached.

As it can be seen from the image that freezing is when energy is removed from the system at 0 ⁰ while melting is when energy is added at 0⁰.

Also when energy is added at 100⁰C, it causes boiling while when it is removed at 100⁰C, it causes condensation.

Melting point of water is 0⁰C while boiling point is 100⁰C
