Lithium relative mass
WebLithium ( Li ) Standard atomic mass: [6.941 (2)] u. Naturally occurring lithium is composed of two stable isotopes 6 Li and 7 Li, the latter being the more abundant (92.5% natural … WebThe relative molecular mass is the weighted average of a molecule’s mass relative to one-twelfth of the mass of a carbon-12 atom (Mr or RMM). To calculate the relative mass of a molecule, simply add the relative masses of its constituent elements. This is simple if the relative atomic masses of the elements involved are known.

WebFor example, the atomic mass of Lithium is 6.941 Da. On the basis of the abundance of isotopes, we can calculate the isotopic mass and average atomic mass of an element. The average mass of element E can be expressed as: m ( E) = ∑ n = 1 m ( I n) × p ( I n) For example, the mass and abundance of isotopes of Boron are given below. S.No. Web1 egg mass = 60g and 1 dozen = 12. Therefore, 1 dozen of egg masses = 1 dozen of 60g = 12 of 60g = 12 x 60g = 720g Example 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu = 1 mole of 12 x 1.6605 x 10^ (-27) kg
