Moles of a Compound
« on: November 07, 2011, 01:47:33 PM »
Hi Guys,

Imagine I have bromobenzene in a chemical reaction/equation... and I have the coefficient of "two" in-front of it because I am using two equivalents.

I used 2.0g of bromobenzene and the molar mass of bromobenzene is 157.01g/mol. The question asks how many moles of bromobenzene I used.

How would I do such a question?

Would I simply divide 2.0g by 157.01g/mol and get 0.0127mol and that would give me the value of the number of moles I used, or should I then divide that number by two (0.0127mol/2) because my coefficient is two in-front of the bromobenzene?

Thanks!

Nevermind, I got it understood. The answer would simply be 0.0127mol! :)
