Question
Quito, Ecuador is at 9,350 above sea level where the atmospheric pressure is 0.72 ATM. A (MW-28 g/mol) on a very hot day (T 37 degrees C) and found to be 120 concentration in mg/m-3 of this sample if the bag is analyzed in Mexico City (T 29 you've made about this problem in the essay box below. sea level where the atmospheric pressure is 0.72 ATM. A bag sample (mylar) is taken of Carbon Monoxide ) on a very hot day (T 37 degrees C) and found to be 120 mg/m-3. Given that the gas constant is 0.082, what is the degrees C, p-0.76 ATM)? You may state any assumptions degrees C, P- o. Select one: a 130 O b 67 151 d. 120 mment on the above question or add notes about your solution.Explanation / Answer
P1*V1 = n*R*T
P2*V2 = n*R*T
Here V = m/rho
Hence,
(P1/rho1)/(p2/rho2) = T1/T2
P1*rho2/rho1*P2 = T1/T2
T2*P1*rho2=T1*rho1*P2
(29+273)*0.72*rho2=(273+37)*120*0.76
rho2=(273+37)*120*0.76/ (29+273)*0.72
=130 mg/m^3
