An element A has a triiodide with the formula AI3 and a trichloride with the formula ACl3. The triiodide is quantitatively converted to the trichloride when it is heated in a stream of chlorine, according to the reaction AI3 +3/2 CI2 →ACI3 +3/2 I2 If 0.8000 g AI3 is treated, 0.3776 g ACl3 is obtained.(a) Calculate the atomic mass of the element A.(b) Identify the element A.
