PLS PLS PLS I NEED HELP Atomic mass or weights are based on a scale on which carbon had an atomic mass of 12.00. Carbon and calcium combine in the ratio of 2:1 to form calcium carbide. If 22.75 g or calcium combine with 13.62 g carbon, what is the atomic weight do calcium? Show work.

"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."

i think its 5049.

i hope this !
