Question

If for every 2 atoms of Chlorine-35 there are 5 atoms of Chlorine-38. What is the average mass?

1 Answer

  • Answer:

    37.1

    Explanation:

    mass of 2 atoms of chlorine-35 = 2× 35 = 70

    mass of 5 atoms of chlorine-38 = 5 × 38 =  190

    average mass = total mass / total number of atoms

                            = (70 +190) / (2 +5)

                            =  260 / 7

                            = 37.143

                            = 37.1
