Question

How many moles of Br atoms are in 0.5 mol of Br2 molecules?

Answer 1

Solution:

Br₂ → 2Br

According to the equation above: Moles of Br₂ = Moles of Br atoms / 2

Hence,

Moles of Br atoms = 2 × Moles of Br₂ = 2 × 0.5 mol = 1.0 mol

Moles of Br atoms = 1.0 mol

Answer: 1.0 mol of Br atoms
