The law that states the volume and absolute temperature of a fixed quantity of gas are directly proportional under constant pressure conditions would be the Charles Law. It <span>is an experimental gas </span>law<span> that describes how gases tend to expand when heated. Hope this answers the question.</span>
Answer:
d = PM / RT
Explanation:
Density can be measure from,
PV = nRT
in this equation
P = pressure
V = volume
n = number of moles
R = general gas constant
T = temperature
It is known that,
number of moles = mass/ molar mass
n = m/M
We will put the n= m/M in PV= nRT
PV = m/M ×RT ......... (1)
density = mass/volume
d= m/v
By rearranging equation (1)
P V/m = RT/M
P = m/V×RT/M
P = dRT/M
d = PM / RT
By using the following formula we can calculate the volume;
C1V1 = C2V2
let V1 is the volume we have to find, then
C1 = 12.1m
C2 = 0.250m
V2 = 5 l
Now, C1V1 = C2V2
12.1 x V1 = 0.250 x 5
V1 = 1.25 / 12.1
V1 = 0.1033 l
thus, the 0.1033 liter of HCl is necessary.
