Answer:

0.09 moles of Br₂

Explanation:

Bromine liquid it refers at Br₂ molecule which is liquid at room temperature.

Now to calculate the number of moles we use the following formula:

number of moles = mass (g) / molecular mass (g/mol)

For Br₂ molecule we have:

number of moles = 14.4 / 160 = 0.09 moles of Br₂

Answer:

The number of moles of bromine liquid produced is 0.09.

Explanation:

Moles = [tex]\frac{\text{Mass of compound}}{\text{Molar mass of compound}}[/tex]

Mass of bromine liquid = 14.4 g

Molecular mass of bromine liquid [tex]Br_2[/tex]= 160 g/mol

Moles of bromine liquid = [tex]\frac{14.4 g}{160 g/mol}=0.09 mol[/tex]

The number of moles of bromine liquid produced is 0.09.
