If 1.0 mole of NaI (aq) is mixed with an excess amount of Pb(NO3)2, how many moles of product will be produced.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

50.23 i believe is correct but don't quote me on that.
