Question

Two acids, HBr and HXO₃, are produced when a compound with a formula of XO₂Br reacts with water. HXO₃ has one acidic hydrogen, which reacts with KOH. A sample of XO₂Br weighing 6.295 g was added to 100.0 mL of water. The solution obtained was titrated with KOH. Determine the atomic mass and identity of the element X if 100.0 mL of 1.000 M KOH is required to neutralize all the acid.

Accepted Answer

Atomic weight = 14.00 g/mol; X is nitrogen.

Answer

Atomic weight = 32.00 g/mol; X is sulfur.

Answer

Atomic weight = 12.01 g/mol; X is carbon.

Answer

Atomic weight = 30.97 g/mol; X is phosphorous.
