What weight of copper(II) oxide, CuO, would theoretically be produced from 1.623 grams of copper? (mol. masses Cu = 63.55; O = 16.00)
*September 22, 2010*

**Chemistry**

So from 1.623 g of Cu, I'd get: ANS: 1.252 X 1.623 g of Cu = 2.032 g OR ANS: 1.623 g of Cu/1.252 = 1.296 g? OR ANS: 1.623 - 1.252 = 0.371 g I am still confused what you mean by that question.
