What is the mass of one mole of Iodine?

Answer 1

The number 115 is the mass number, so the mass is 115 amu. One amu (Atomic Mass unit) is about 1.66 x 10-27 kg, so if your looking for the mass of one atom of In-115, multiply 1.66 x 10-27 kg by 115. That's about 1.9 x 10-25 kg. You chemistry teacher should have taught you this, and probably did, if you were paying attention in class.

Answer 2

The mass number is the number of protons and neutrons in the nucleus. As isotopes of an element have differing numbers of neutrons you must always check what isotopes exist.

Indium has a number of stable isotopes:

113In with 64 neutrons, 39 protons and % in nature of 4.3%

115In with 66 neutrons, 39 protons and % in nature of 95.7%

Answer 3

I = 126.9 ~ 127

Molecular Formula of Iodine = I2

therfore 1 mole of iodine = 127 x 2 = 254

Answer 4

Iodine is a metal element. Atomic mass of it is 127.

Answer 5

Indium is a metal element. Atomic mass of it is 49.

Answer 6

1atom I x (1mol I/6.022 X 10^23) x (128.90g I/1mol I)= 2.140 x 10^-22

Answer 7

Indium is a metal element. Atomic mass number of it is 115.

Answer 8

Indium (In) has an atomic weight of 114.818g/mol

Answer 9

Mass of Iodine is 126.9045

Answer 10

126
