Answer: The correct answer is : 44.1 g / mol
Explanation: d = PM / RT
M = dRT / P
d = 1.97 g / l
R = ideal gas (0.082 06 l - atm / mol - ° K)
P = 1 atm
T = 273 ° K
M = Molar mass
M = 1.97 g / l x 0.082 l - atm / mol - ° K x 273 ° K / 1 atm
M = 44.1 g / mol
Answer:
The correct answer is
M = 44.1 g / mol
Explanation:
Hello!
Let's solve this!
First we write down the data
d: 1.97 g / L
P: 1 atm
R: 0.082 atmL / Kmol
T: 273K
From the ideal gas formula:
d = P * M / R * T
We cleared M to know the molar mass.
M = (d * R * T) / P
M = (1.97 g / L * 0.082 atmL / Kmol * 273K) / 1atm
The correct answer is
M = 44.1 g / mol
