Melanoma is the main complication of moles. Some people have a higher than average risk of their moles becoming cancerous and developing into melanoma. Factors that increase your risk of melanoma include:. The following measures can help limit the development of moles and the main complication of moles — melanoma.
Become familiar with the location and pattern of your moles. Regularly examine your skin to look for changes that may signal melanoma. Do self-exams once a month, especially if you have a family history of melanoma.
With the help of mirrors, do a head-to-toe check, including your scalp, palms and fingernails, armpits, chest, legs, and your feet, including the soles and the spaces between the toes. Also check your genital area and between your buttocks. Talk with your doctor about your risk factors for melanoma and whether you need a professional skin exam on a routine basis. Take measures to protect your skin from ultraviolet UV radiation, such as from the sun or tanning beds.
UV radiation has been linked to increased melanoma risk. And children who haven't been protected from sun exposure tend to develop more moles. Mayo Clinic does not endorse companies or products.

We use the most common isotopes. This is how to calculate molar mass average molecular weight , which is based on isotropically weighted averages.
This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
