A 2.5g sample of impure Copper was analyzed by allowing it to react with 45mL of 5M Nitric Acid to form Copper (II) Nitrate, Nitrogen Dioxide, and Water. Of the Nitric Acid, .0125mol remained. Assuming impurities do not react, what is the % Copper in the impure sample?

Check your post/numbers. I think you have more copper in the sample than 2.5 grams and that can't be.
