1. Calculate the pH of the solutions, given the following [H+], and then identify the solution as acidic, basic, or neutral. a) [H+] = 1.2 x 10-2 M

b) [H+] = 5.8 x 10-9 M

c) [H+] = 3.92 x 10-12 M

d) [H+] = 4.52 x 10-5 M

58750.08068 is the answer i think

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
