Question

Quizplus · Accepted Answer

The percent composition of an element in a compound is calculated by dividing the mass of the element in the compound by the total mass of the compound, then multiplying by 100. Here, the total mass of the compound X is 0.540 g (Br) + 0.858 g (I) = 1.398 g. The percent composition of Br is (0.540 g / 1.398 g) * 100 = 38.6%, and for I, it is (0.858 g / 1.398 g) * 100 = 61.4%.
