how many moles of copper...?

Question

im studying for a lab exam for chemistry, and on our review we have a question i cannot figure out.

it says

a 7.302 sample of CuCl2 yields 100% of the copper in the sample. how many moles of copper should be obtained from this sample.
(1 g-atom of Cu = 63.55 Cu; 1 g atom of CL = 35.45g Cl)

im looking for someone to explain the way to go about to get the answer, so i can do it on the exam.

thanks allooot. i hate chemistry, im so bad at it.

Answer 1

Find the % copper in the sample:

63.55 + 70.90 = 134.45

Cu% = 63.55 / 134.45 = ?
Calculate the answer above (in decimal form) then multiply the sample size: 7.302 g by the decimal from above.
