Molar volume means that 1 mol of any gas occupies a volume of 22.4 L at standard temperature and pressure conditions.
the molar mass of Ar is 40 g/mol
this means that a mass of 40 g occupies a volume of 22.4 L
therefore a mass of 120 g of Ar occupies a volume of - 22.4 L / 40 x 120
therefore volume occupied by Ar - 67.2 L
Answer:
trial 1: % error = 3.546 %
trial 2: % error = 3.073 %
trial 3: % error = 0.946 %
Explanation:
- % error = ((ΔHi - ΔH) / ΔH) ×100
∴ ΔH = - 42.3 KJ/mol
trial 1:
∴ ΔH1 = - 43.8 KJ/mol
⇒ % error = ((-43.8 - ( -42.3 )) / ( -42.3 ))×100
⇒ % error = (0.03546)*100 = 3.546 %
trial 2:
∴ ΔH2 = - 41.0 KJ/mol
⇒ % error = ((-42.3 - ( -41.0 )) / ( -42.3 ))×100
⇒ % error = (0.03073)*100 = 3.073%
trial 3:
∴ ΔH3 = - 42.7 KJ/mol
⇒ % error = ((-42.7 - ( -42.3 )) / ( -42.3 ))×100
⇒ % error = (9.456 E-3)*100 = 0.946 %
