A sample of aluminium metal (15.0 g) is reacted with chlorine gas at 1 atm and 25 °C. The chlorine is supplied as 10.0 L of gas at these conditions. The reaction is: \(2\,\mathrm{Al} + 3\,\mathrm{Cl_2} \rightarrow 2\,\mathrm{AlCl_3}\). (i) Determine the theoretical mass of aluminium chloride that can be formed. (ii) If 30.0 g of \(\mathrm{AlCl_3}\) are actually obtained, calculate the percent yield.

Answer Options

Correct Answer A. Theoretical mass = 36.3 g; percent yield = 82.6 %
B. Theoretical mass = 36.3 g; percent yield = 75.0 %
C. Theoretical mass = 30.0 g; percent yield = 100 %
D. Theoretical mass = 45.0 g; percent yield = 66.7 %
Correct Answer
A
Correct Option:
Theoretical mass = 36.3 g; percent yield = 82.6 %
