The relative atomic mass (A r) of atoms is the average mass of all the different isotopes of an element (taking into account the amount of each isotope) on a scale where 12C atoms have a mass of exactly 12. Imagine you have 90 balls with mass 200 g, and 10 balls with mass 300 g. The average mass of the balls is given by:

“Molar mass” is used to describe the mass of one mole of a chemical compound, while “atomic mass” is used to describe the mass of one mole of an element or the mass of one atom of an element. 8) Which is a better unit for expressing molar mass, “amu” or “grams/mole”?

Calculate the relative atomic mass (Ar) of magnesium, accurate to two decimal places. 24 Question 14 Calculate the mass, in g, of one mole of hydrated copper(II) sulfate, CuSO45H2O, given the following relative atomic mass values?

In the case of single elements or individual atoms, the molar mass is simply the element's mass given in atomic mass units. In other words, an atom's atomic mass and molar mass are the same. Molar mass is equivalent to atomic mass for individual atoms, …
