The molar mass of the N 2 molecule is therefore 28.02 g/mol.
Sodium is an alkali metal, being in group 1 of the periodic table. 1 The molar mass of Iodine is 126.90 g/mol. It is a soft, silvery-white, highly reactive metal. The molar mass of Sodium is 22.990 g/mol. This is referred to as the molecular mass and the molecular mass of any molecule is simply the sum of the atomic masses of all of the elements in that molecule. Sodium is a chemical element it has symbol Na (from Neo-Latin natrium) and atomic number 11. It has an atomic weight of 22.98977 and a mass number of 23. Specific Heat: Value given for solid phase. Critical Temperature: Value estimated based on extrapolation. Critical Pressure: Value estimated based on extrapolation. When the chemical elements are thus arranged, there is a recurring pattern called the periodic law in their properties, in which elements in the same column (group. Click any property name to see plots of that property for all the elements. Now we interpret the coefficients as referring to molar amounts, not individual molecules. For nitrogen, the mass of the N 2 molecule is simply (14.01 + 14.01) 28.02 amu. Sodium is the 11th element in the periodic table and has a symbol of Na and atomic number of 11. periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number i.e., the total number of protons in the atomic nucleus.

We can leave out the word mol and not write the 1 coefficient (as is our habit), so the final form of the equation, still balanced, is But 6.022 × 10 23 is 1 mol, while 12.044 × 10 23 is 2 mol (and the number is written that way to make this more obvious), so we can simplify this version of the equation by writing it as These coefficients also have the ratio 2:1:2 (check it and see), so this equation is balanced.
