Healing time is different depending on the part of your body that you get pierced. Some parts are more likely to get infected or have problems. Piercings on your ear lobes usually take about 6-8 weeks to heal. However, piercings on the side of your ear (cartilage) can take anywhere from 4 months to 1 year to heal.
By Anne Marie Helmenstine, Ph.D. Molecular Equation Definition: A molecular equation is a balanced chemical equation where the ionic compounds are expressed as molecules instead of component ions. Examples: KNO 3 (aq) + HCl(aq) â KCl(aq) + HNO 3 (aq) is an example of a molecular formula.
Molecular mass is defined as the sum of the atomic masses of the atoms. (or ions) in a MOLECULE. The unit is always amu. For example: 1 Fe atom has a mass of 55.85 amu 1 O atom has a mass of 16.00 amu but O2 has a mass of 32.00 amu.
