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

The question does not state the chemical equation or the reactant aside from BaBr2.

The complete question should be

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

BaBr2 + K2SO4 → KBr + BaSO4

Answer:-

14.98 moles

Explanation:-

From the balanced chemical equation

BaBr2 + K2SO4 → KBr + BaSO4

We see

From 1 mole of BaBr2 1 mole of KBr is produced.

From 14.98 moles of BaBr2 then 1 mole x 14.98 mole / 1 mole

= 14.98 moles of KBr will be produced.

14.98 moles of KBr will be produced from 14.98 moles of BaBr2
