(Answered) The halogen bromine br2 is a liquid at room temperature

Academics

The halogen bromine (Br₂) is a liquid at room temperature (25^oC) and somewhat soluble in water.

A saturated solution of Br₂ contains 3.3 x 10^-4 g Br₂ dissolved in 1 g H₂O at room temperature.

A saturated solution of Br₂ in water at 0C contains 4.2 x 10^-4 g Br₂ in 1 g H₂O.

Calculate the mole fraction of bromine in water in both solutions.

Calculate the molality of bromine in both solutions presuming that the density of water is 1 g/cm³.
