Answer: cash?
Explanation: oh and it’s d
The answer is most definitely “A”
Answer:
365.4 g/mol is the molar mass of this gas.
Explanation:
Using ideal gas equation:
PV = nRT
where,
P = Pressure of gas = 0.98 atm
V = Volume of gas = 1.5 L
n = number of moles of gas = ?
R = Gas constant = 0.0821 L.atm/mol.K
T = Temperature of gas = 287 K
Putting values in above equation, we get:
![(0.98 atm)\times 1.5 L=n\times (0.0821 L.atm/mol.K)\times 287K\\\\n=0.06239 mole](https://tex.z-dn.net/?f=%280.98%20atm%29%5Ctimes%201.5%20L%3Dn%5Ctimes%20%280.0821%20L.atm%2Fmol.K%29%5Ctimes%20287K%5C%5C%5C%5Cn%3D0.06239%20mole)
Moles of gas = n = 0.06239 mol
Mass of gas = m = 22.8 g
Molar mass of gas = M
![0.06239=\frac{22.8 g}{M}](https://tex.z-dn.net/?f=0.06239%3D%5Cfrac%7B22.8%20g%7D%7BM%7D)
![M=\frac{22.8 g}{0.06239 mol}=365.4 g/mol](https://tex.z-dn.net/?f=M%3D%5Cfrac%7B22.8%20g%7D%7B0.06239%20mol%7D%3D365.4%20g%2Fmol)
365.4 g/mol is the molar mass of this gas.
Answer:
they're different because one is carbon and the other is cabohydride
Explanation:
CH is a mix between carbon and hydrogen C is carbon
