Homework Help: Chemistry :)

Posted by Miley on Wednesday, February 6, 2008 at 3:52pm.

Cr2O3 + 3CCl4 ---> 2CrCl3 + 3CCl2O

In one experiment, 6.37 grams of Cr2O3 was treated wiht excess CCl4 and yielded 8.75 grams of CrCl3. What was the percent yeild?

I have no idea how to do this. I know that percent yield is actual/theorectical yield *100.
And i know how to do this type of problem when the problem has the words is produced in it. Because what is produced is the actual yield. But how would i do this problem since it doesn't say is produced?

Can anyone help me, thanks:)
