If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18.
<h3>What is an ideal gas equation?</h3>
The ideal gas equation is given below.
![PV = nRT](https://tex.z-dn.net/?f=PV%20%3D%20nRT)
The equation can be written as
![\rm PV = \dfrac{m}{M} \ RT\\\\\\MPV = mRT](https://tex.z-dn.net/?f=%5Crm%20PV%20%3D%20%5Cdfrac%7Bm%7D%7BM%7D%20%5C%20RT%5C%5C%5C%5C%5C%5CMPV%20%3D%20mRT)
Where M is the molar mass, P is the pressure, V is the volume, R is the universal gas constant, T is the temperature, and m is the mass of the gas.
Then the molar mass of a 0.622-gram sample of gas has a volume of 2.4 L at 287 K and 0.850 atm.
V = 2.4 L = 0.0024
P = 0.85 atm = 86126.25 Pa
T = 287 K
m = 0.622
R = 8.314
Then we have
![\begin{aligned} \rm M \times 86126.25 \times 0.0024&= 0.622 \times 8.314 \times 287\\\\\rm M &= 7.18 \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%20%5Crm%20M%20%5Ctimes%2086126.25%20%5Ctimes%20%200.0024%26%3D%200.622%20%5Ctimes%20%208.314%20%5Ctimes%20287%5C%5C%5C%5C%5Crm%20M%20%26%3D%207.18%20%5Cend%7Baligned%7D)
Then the molar mass of the gas is 7.18.
