Atomic Mass Formula Atomic mass in an atom or group of an atom is the sum of the masses of protons neutrons and electrons. A convenient amount unit for expressing very large numbers of atoms or molecules is the mole. Force is measured in N newton which you can also write as kg m s 2.
According to Newtons second law Fma the acceleration of an object is directly proportional to the force applied to it.
The formula for the amount of an element in a compound is. Just like the molecular mass it is calculated by adding the atomic masses of the atoms present in one formula unit. The molar mass M is a physical property and it is defined as the mass of one mole of the chemical substance or it is a ratio of the mass of a chemical compound to its amount of chemical substance. Each and every atom has a mass given by amu units.
