Question

Select the correct answer.

Answer 1

Ans: 4.73 moles

Given reaction:

2LiBr + Ba → BaBr2 + 2Li

Mass of Ba = 325 g

Atomic mass of Ba = 137.32 g/mol

# moles of Ba = 325/137.32 = 2.368 moles

Based on the reaction stoichiometry:

1 mole of Ba produces 2 moles of Li

Therefore, 2.368 moles of Ba will produce, 2.368*2 = 4.736 moles
