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
