Question

If 29.92 g of a pure element contains 8.983×10^22 atoms, what is the element?

Answer 1

Okay, so like this question is pretty simple. I changed atoms to moles using avagadro's number. Once I got the moles I calculated the molar mass using the 29.92. But my answer is 200. There aren't any elements with a 200 atomic number. Any help?

mercury is the closest at 200.59

Answer 4

Ohhhh, shoot I was confusing atomic number with atomic mass. *facepalm* thank you!
