Add your answer. If you were asked to describe metals and magnetism you could say that? A)all metals are attracted to magnets because they are able to create their own magnetic field. B)all metals are attracted by magnets; this is why we call metals ferromagnetic. C)only some metals are attracted to magnets because they do not have a magnetic field. D)only some metals are attracted by magnets;...
The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah. The mass of a single lead atom is 207.2 AMUs (atomic mass units) which when converted to grams weighs 3.440e-22 grams. Huzzah.
) The relative abundance is simply the percentage of the isotope, but in decimal format. 0.90% corresponds to a relative abundance of 0.6090. Average atomic mass of copper = (62.93 amu Ã 0.6909) + (64.94 amu Ã 0.3091)= 63.55. From the calculation, we know that an AVERAGE atom of copper has a mass of 63.55 amu. Notice that in this problem, we would predict that the average is closer to the weight of the lighter isotope.
