Homework Help: Chemistry

Posted by Amy~ on Thursday, September 2, 2010 at 9:15pm.

I have a test tommorow and I forgot how to do this:

Caculate mass of Cr in 548g of K2Cr2O7.

I remember putting 548g K2Cr2O7 (1 mol K2Cr2O7/294.2 g K2Cr2O7) then from there I forgot.

I got 96.85 g Cr but that does not seem right.

Could someone please tell me the steps
