yes, I realized that.Gokul43201 said:
Molecular weight is the mass of a molecule, typically expressed in units of daltons or atomic mass units (amu). It is the sum of the atomic weights of all the atoms in a molecule.
Molecular weight is calculated by adding together the atomic weights of all the atoms in a molecule. This can be done using a periodic table to find the atomic weights of each element and then multiplying by the number of atoms present in the molecule. The sum of these values is the molecular weight.
Molecular weight is important in chemistry because it is used to determine the amount of a substance needed for a reaction, to calculate concentrations of solutions, and to understand the physical properties of substances. It is also necessary for converting between different units of measurement and for identifying unknown substances.
Molecular weight can have a significant impact on a substance's properties. Generally, substances with higher molecular weights tend to have higher boiling and melting points, lower vapor pressures, and are less soluble in solvents. This is because larger molecules have stronger intermolecular forces, making it more difficult to break them apart.
Yes, molecular weight can be used to determine a substance's chemical formula. By finding the molecular weight of a substance and comparing it to the molecular weight of known compounds, scientists can identify the elements present in the substance and determine its chemical formula.
