Quizplus · Accepted Answer

According to the given reaction, 2 moles of Al react with 3 moles of Br2 to produce 2 moles of AlBr3.

The molar mass of Br2 is 159.8 g/mol, which means 100 g of Br2 is 0.626 mol.

Using stoichiometry,

2 moles of AlBr3 = (2/3) x 0.626 mol = 0.417 mol

The molar mass of AlBr3 is 266.7 g/mol, which means 0.417 mol is 111 g.

Therefore, 111 g of AlBr3 is produced when 100 g of Br2 reacts, confirming that the statement is true.
