The volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.
<h3>How to calculate volume?</h3>
The volume of a given gas can be calculated using the following Charle's law equation:
V1/T1 = V2/T2
Where;
- T1 = initial temperature
- T2 = final temperature
- V1 = initial volume
- V2 = final volume
- V1 = 9L
- V2 = ?
- T1 = 325K
- T2 = 450K
9/325 = V2/450
325V2 = 4050
V2 = 4050/325
V2 = 12.46L
Therefore, the volume of a gas that occupies 9 L at a temperature of 325K is 12.46L.

Answer:
Explanation:
Hermione is pretty smart. She realizes that, according to Dalton's Law of Partial Pressures, each gas exerts its pressure independently of the others, as if the others weren't even there.
She shows Ron how to use the Ideal Gas Law to solve the problem.
pV = nRT
She collects the data:
V = 1.00 L; n = 0.0319 mol; T = 25.0 °C
She reminds him to convert the temperature to kelvins
T = (25.0 +273.15) K = 298.15 K
Then she shows him how to do the calculation.

Mass number is equal to the sum of number of neutrons (neutral subatomic particle) and number of protons (positively charge particle).
Mass number =
Now, atomic number is same as the number of protons i.e. atomic of nitrogen is 7 . Thus, number of protons is also equal to 7.
Therefore,
Mass number =
= 
Hence, mass number of nitrogen is equal to .
The concentration refers to the amount of substance that is contained in solution.
<h3>What is the concentration?</h3>
The concentration refers to the amount of substance that is contained in solution. We can be able to obtain the concentration of the raw acid by the use of the relation;
Co = 10pd/M
M = molar mass of the acid
p = percentage of the acid
d = density of the acid
Co = 10 * 36 * 1.18/36.5
Co = 11.6 M
Using the dilution formula;
C1V1 = C2V2
10 * 11.6 = C2 * 1000
C2 = 10 * 11.6/1000
C2 = 0.116 M
Using again;
C1V1 = C2V2
0.116 * 5 = C2 * 20
C2 = 0.116 * 5 /20
C2 = 0.029 M

Solutes are when a substance is dissolved into another substance, so if it's dissolved, it is combined completely, and you can't see it anymore :)
