Excess F(2)(g) reacts at 150^(@)C and 1....

Excess `F_(2)(g)` reacts at `150^(@)C` and 1.0 atm pressure with `Br_(2)(g)` to give a compound `BrF_(n)`. If 423 mL of `Br_(2)(g)` at the same temperature and pressure produced 4.2 g of `BrF_(n)`, what is n? [Atomic mass Br =80, F =19 ]

Text Solution

Verified by Experts

The correct Answer is:
5
`n_(Br_(2))=(1xx0.423)/(0.0821xx423)=(1)/(82.1) "mole"`
POAC on 'Br'
`(1)/(82.1)xx2=(4.2)/(80+19n)xx1`
`n=5`
