Asked by richard

How many moles are in 13grams of C6H6. should this question be broken down into its imperical formula (CH)6 and calculate the number of moles of CH and multiply by 6 or calculate the gram molecular wt of C6H6 and divide it into 13 grams? I took 13 grams and divided it by the gram molecular wt of 78 and the answer was wrong. Now I am confused.

Richard, I answered this question for you before. 13/78.11 is the correct answer. If you will show you work I'll try to find the error. To how many significant figures are you to give the answer? And why do you think it is wrong?
