MX3 is formed from the reaction between an unidentified metal M and an unidentified halogen X. The compound decomposes when heated and produces MX and X2.
MX3(s) → MX (s) + X2(g)
When 1.18 g of MX3 is heated, 1.07 g of M and 34.76 mL of X2 gas are obtained. The volume of 1.00 mol of X2 under the reaction condition is 22.41 L. Determine the identity of halogen X and its atomic weight.
