A molecule has an empirical formula of ch, and its molar mass is known to be 26 g/mol and the  molecular formula is C₂H₂ ethyne

Molecular formula of compound is (CH)n and the given molar mass is 26g/mol

Molar mass of (CH)n, C=12=n(12+1)=13n

So 13n and n=2

=13×2=26 and given molar mass is also 26g/mol

So here two carbon and two hydrogen so molecular formula is C₂H₂ and name is ethyne

schepotkina [342]

Answer:

B = - 0.0326 dm³/mol

Explanation:

virial eq until second term:

  • PVm = RT [ 1 + B/Vm ]

∴ P = 10 bar * (atm/ 1.01325 bar) = 9.869 atm

∴ T = 200°C = 473 K

∴ Vm = 3.90 dm³/mol

∴ R = 0.08206 dm³.atm/K.mol

⇒ PVm / RT = 1 + B/Vm

⇒ ((9.869 atm)*(3.90 dm³/mol)) / ((0.08206 dm³.atm/mol.K)*(473K)) = 1 + B/Vm

⇒ 0.99164 = 1 + B/Vm

⇒ B/Vm = - 8.357 E-3

⇒ B = (3.90 dm³/mol)*( - 8.357 E-3 )

⇒ B = - 0.0326 dm³/mol
