What is the molar mass of each of the following elements? a) nitrogen, N2(g)
c) chlorine, Cl2(g)
b) fluorine, F2(g)
d) iodine, 12(s)

a. Nitrogen = 28

b. Flourine = 38

c. Chlorine = 70.9

d. Iodine = 253.8

Explanation:

a. Nitrogen

Atomic mass is 14

Molar mass is 14 x 2 = 28

b. Flourine

Atomic mass is 19

Molar mass is 19 x 2 = 38

c. Chlorine

Atomic mass is 35.45

Molar mass is 35.45 x 2 = 70.9

d. Iodine

Atomic mass is 126.9

Molar mass is 126.9 x 2 = 253.8

a)28.02 g/mol.

c)70.90 g/mol

b)38.00 g/mol

d)253.80 g/mol

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

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.
