Molecular Weight Of Potassium
Molecular Weight: An Overview
The mole weight, also known as molar mass, is a fundamental concept in chemistry. It represents the mass of one mole of a particular substance and is typically expressed in grams per mole (g/mol). A mole is a unit used to quantify the amount of a substance and contains approximately 6.022 x 10^23 entities, known as Avogadro’s number. Molecular weight is numerically equivalent to the atomic or mole weight of the substance.
The Molecular Weight of Potassium (K)
Potassium exists naturally in the form of various isotopes, but the most abundant and stable isotope is potassium-39 (^39K). To calculate the mole weight of potassium, we consider this dominant isotope.
The atomic mass of potassium-39 is approximately 38.963 g/mol. Therefore, the mole weight of potassium (K) is:
