How to Calculate the Atomic Mass of Contaminated Iodine?

In summary, the atomic mass of contaminated iodine can vary depending on the specific isotopes present in the contamination and generally ranges from 126.90447 to 126.90848 grams per mole. Contamination can alter the atomic mass of iodine by introducing additional isotopes or altering the ratio of existing isotopes. This can have negative health effects as iodine is essential for thyroid function, and exposure to contaminated iodine can lead to thyroid disorders. The atomic mass of contaminated iodine can be determined through various analytical techniques, such as mass spectrometry. Sources of contamination for iodine include nuclear accidents, industrial processes, improper disposal of radioactive materials, and natural occurrence in certain areas with high levels of radioactive elements in the soil.

Homework Statement


Naturally occurring iodine has an atomic mass of 126.9045. A 12.3849-g sample of iodine is accidentally contaminated with 1.00070 g of ,129I a synthetic radioisotope of iodine used in the treatment of certain diseases of the thyroid gland. The mass of129I is 128.9050 . Find the apparent "atomic mass" of the contaminated iodine.

How do you calculate atomic mass knowing isotopic composition? Do you know what 'weighted average' is?

FAQ: How to Calculate the Atomic Mass of Contaminated Iodine?

What is the atomic mass of contaminated iodine?

The atomic mass of contaminated iodine can vary depending on the specific isotopes present in the contamination. Generally, the atomic mass of iodine ranges from 126.90447 to 126.90848 grams per mole.

How does contamination affect the atomic mass of iodine?

Contamination can alter the atomic mass of iodine by introducing additional isotopes or altering the ratio of existing isotopes. This can lead to a higher or lower atomic mass, depending on the type and amount of contamination.

What is the impact of contaminated iodine on health?

Contaminated iodine can have various negative health effects, as iodine is an essential element for thyroid function. Exposure to contaminated iodine can lead to thyroid disorders, such as goiter or thyroid cancer.

How is the atomic mass of contaminated iodine determined?

The atomic mass of contaminated iodine can be determined through various analytical techniques, such as mass spectrometry. This allows for the identification and quantification of the different isotopes present in the contamination.

What are the sources of contamination for iodine?

Iodine contamination can come from various sources, including nuclear accidents, industrial processes, and improper disposal of radioactive materials. It can also be naturally occurring in certain areas with high levels of radioactive elements in the soil.
