Here's how to calculate the number of moles in 160g of bromine molecules:

1. Determine the Molar Mass of Bromine

* Bromine exists as a diatomic molecule (Br₂).

* The atomic mass of bromine is approximately 79.9 g/mol.

* The molar mass of Br₂ is 2 * 79.9 g/mol = 159.8 g/mol

2. Calculate Moles

* Use the formula: moles = mass / molar mass

* moles = 160 g / 159.8 g/mol

* moles ≈ 1.00 mol

Therefore, there are approximately 1.00 moles in 160g of bromine molecules.
