Answer: The volume of tank is 17.5 L.
Explanation:
Given: Mass of methane = 173 g
Pressure = 15.1 atm
Temperature = 298 K
Molar mass of methane is 16.04 g/mol.
Therefore, moles of methane are calculated as follows.
![No. of moles = \frac{mass}{molar mass}\\= \frac{173 g}{16.04 g/mol}\\= 10.78 mol](https://tex.z-dn.net/?f=No.%20of%20moles%20%3D%20%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D%5C%5C%3D%20%5Cfrac%7B173%20g%7D%7B16.04%20g%2Fmol%7D%5C%5C%3D%2010.78%20mol)
Now, ideal gas equation is used to calculate the volume as follows.
PV = nRT
where,
P = pressure
V = volume
n = no. of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the values into above formula as follows.
![PV = nRT\\15.1 atm \times V = 10.78 mol \times 0.0821 L atm/mol K \times 298 K\\V = \frac{10.78 mol \times 0.0821 L atm/mol K \times 298 K}{15.1 atm}\\= 17.5 L](https://tex.z-dn.net/?f=PV%20%3D%20nRT%5C%5C15.1%20atm%20%5Ctimes%20V%20%3D%2010.78%20mol%20%5Ctimes%200.0821%20L%20atm%2Fmol%20K%20%5Ctimes%20298%20K%5C%5CV%20%3D%20%5Cfrac%7B10.78%20mol%20%5Ctimes%200.0821%20L%20atm%2Fmol%20K%20%5Ctimes%20298%20K%7D%7B15.1%20atm%7D%5C%5C%3D%2017.5%20L)
Thus, we can conclude that volume of the tank is 17.5 L.
I found that out in a weird book
It had pretty weird things in there and it that this in there too
