Q. What is the molar mass of magnesium?
Answer: In simple terms, the molar mass is the mass of one mole of the substance. It is calculated using the standard atomic weights. In a more standard form, it can be defined as the mass of the compound divided by the substantial amount in that particular sample. The molar mass is independent of the sample size. The units in which it can be expressed generally are kg/mol or g/mol. Magnesium is one of the chemical elements with atomic number 12. The chemical is symbolically represented as Mg in chemistry. It is a solid gray color substance that is shiny. It belongs to the group of alkaline earth metals (group 2). The element can be found naturally but only with other elements combined. It is the eleventh place in terms of the most available element by mass in the human body. The molar mass of magnesium is 24.305 g/mol.
A “mole” of any substance means 6.022 X 1023 atoms of that substance. The first step in calculating molar mass recognises every element in a stated molecule. After that, find the atomic mass of each by observing the periodic table. To get the total atomic mass of an atom, multiply the respective atomic mass with the total number of atoms in that molecule.
The atomic number of the magnesium is 12. The atomic mass of naturally occurring isotopes of magnesium (Mg24, Mg25, Mg26) is 23.98 u, 24.98 u, and 25.98 u. The average atomic mass of Magnesium 24 is around 24 because the element contains 12 neutrons and 12 protons. The average atomic mass of Magnesium 25 is around 25 because it contains 12 protons and 13 neutrons.
