Answer:
a. the density of radon = 0.0908g/m3
b. radon gas concentration will be greater on top of the building than than basement.
Explanation:
the solution to this question can be gotten from ideal gas law.
the ideal gas law is given by :
PV = nRT
where
P = atmospheric pressure in atm = 1 atm
V = volume in m3
n = number of moles
R = the gas constant.
T = temperature in kelvin = 298K
the gas constant R is given as 8.3145J.mol-1.K-1 or 8.2057m3.atm/mol.K.
n= mass of gas divided by molecular mass of gas = m/MM
PV = nRT
V/n = RT/P
V/m =RT/MM.P
density = m/V = (MM*P)/(RT)
the molecular mass of Radon is a constant which is 222g/mol
the density of radon = (222*1)/(8.2057 * 298)
= 0.0908g/m3
b. radon gas concentration will be greater on top of the building than than basement. radon concentration increases as height increases. also radon concentration increases greatly in the afternoon and evening and decreases in the morning. this means temperature affect the concentration.
Answer:
a) The pressure wiil be twice the original value
Explanation:
Pressure in inversely proportional to volume, that means; when one value decreases at the same rate that the other increases, if the temperature and amount of gas remain unchanged within a closed system. The above derived from the same definition of pressure. The pressure is defined as the crashes and frequency of the same agains surface of objects, if certain amount of gas is contained in a recipent, It will crash more times if the volume is minor. The Boyle´s law express this mathematically.
