Respuesta :
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
