Chem:moles question?

How many moles of potassium bromide can be produced from the reaction of 2.92 moles of potassium with 1.78 moles of bromine gas?





2 K(s) + Br2(g) → 2 KBr(s)





a.3.56 mol


b.5.84 mol


c.1.78 mol


d.1.46 mol


e.2.92 mol





is the answer e?


thanks

yes, the answer is e
Reply:Yes. The answer is "e"





All the bromine gas won't be reacted, since 2.92 mol K will only react with (2.92 / 2) 1.46 mol of Br2 before being exhausted.





Since 2 mol KBr are produced for every 2 mol K reacted, 2.92 mol K will produce 2.92 mol KBr
