Mweight

Mweight, or Molecular weight, refers to the sum of the atomic weights of all atoms in a molecule. It is expressed in unified atomic mass units (u) or Daltons (Da). Essentially, it tells you the size or mass of a single molecule by adding up the weights of each individual atom based on their types and quantities. For example, a water molecule (H₂O) weighs about 18 Daltons because hydrogen atoms are about 1 Dalton each, and oxygen is about 16 Daltons. Mweight helps scientists understand how much a molecule weighs, which is important in chemistry, biology, and pharmacology.
