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
