Question 1

A 1.60-g sample of an oxide of bromine is converted to 2.685 g of AgBr. Calculate the empirical formula of the oxide. (molar mass for AgBr = 187.78 g/mol)

◦ BrO₃

◦ BrO₂

◦ BrO
◦ Br₂O
◦ None of these are correct.

Question 2

A 15-g sample of lithium is reacted with 15 g of fluorine to form lithium fluoride:

2Li + F₂→ 2LiF. After the reaction is complete, what will be present?

◦ 2.16 moles lithium fluoride only
◦ 0.789 moles lithium fluoride only
◦ 2.16 moles lithium fluoride and 0.395 moles fluorine
◦ 0.789 moles lithium fluoride and 1.37 moles lithium
◦ none of these are correct
