Ms. Morrison has a bad habit of buying cheap jewelry through Instagram ads. One particularly interesting pendant claimed to be made of “valuable metal,” but didn’t say which metal. Being the scientist that she was, Morrison wanted to determine if the ad was true and the metal was “valuable.” Using the water displacement method and an electronic balance, Ms. Morrison determined that the 50.00 g pendant had a volume of 4.753 cm³. Determine the density of the metal pendant. Show all your work and use the GUESS/GRASS method for full marks. [2A] Write your final answer only in this space. Your full solution will be uploaded in the space below.

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
