1 Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)  Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
Amoxicillin fights bacteria in the body. Clavulanate potassium is a form of clavulanic acid, which is similar to penicillin. Clavulanate potassium fights bacteria that is often resistant to penicillins and other antibiotics.
A study carried out to determine the chemical stability of. amoxicillin and potassium clavulanate (250/62 Co-amoxiclav) oral. suspension stored at room temperature 20Â°C and 8Â°C over a period. of 11 days showed amoxicillin is stable for 7 days at both. temperatures. Potassium clavulanate maintains at least 90% of its.
