Question

How many moles of KBr will be produced from 14.98 moles of BaBr2?

Answer 1

Answer: -

29.96 moles of KBr

Explanation: -

The balanced chemical equation for the formation of KBr from BaBr₂ is

BaBr₂ + K₂SO₄ 2KBr + BaSO₄

From the balanced chemical equation we see

1 mole of BaBr₂ gives 2 moles of KBr

14.98 moles of BaBr₂ gives
`(2 moles KBr x 14.98 moles BaBr2)/(1 mole BaBr2)` moles of KBr

= 29.96 moles of KBr.
