A certain compound of bromine and fluorine is used to make UF6, which is an important chemical in the processing and reprocessin
Aleksandr [31]

Answer: The empirical formula is BrF_3

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of Br=  58.37 g

Mass of F = (100-58.37) = 41.63 g

Step 1 : convert given masses into moles.

Moles of Br=\frac{\text{ given mass of Br}}{\text{ molar mass of Br}}= \frac{58.37g}{80g/mole}=0.73moles

Moles of F =\frac{\text{ given mass of H}}{\text{ molar mass of H}}= \frac{41.63g}{19g/mole}=2.2moles

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Br = \frac{0.73}{0.73}=1

For F = \frac{2.2}{0.7}=3

The ratio of Br: F= 1 : 3

Hence the empirical formula is BrF_3
