How many moles of KBr will be produced from 10.51 moles of BaBr2?

gregori [183]

Answer:

21.02moles of KBr

Explanation:

Parameters given:

Number of moles BaBr₂ = 10.51moles

Complete reaction equation:

BaBr₂ + K₂SO₄ → KBr + BaSO₄

Upon inspecting the given equation, we find out that the atoms are not balanced on both sides of the equation:

The balanced equation is:

BaBr₂ + K₂SO₄ → 2KBr + BaSO₄

From the equation:

1 mole of BaBr₂ produces 2 moles of KBr

∴ 10.51 moles of BaBr₂ will yield (2 x 10.51) moles = 21.02moles of KBr
