Answer» s of CHLORINE element is taken as 35. It exists in two major isotopes such as and . We NEED to take the WEIGHTED AVERAGE of both the isotopes in terms of the percentage of abundance that is present on the earth in order to get the average atomic mass of chlorine and it is calculated as followsLet the percentage of be x, then be (100-x),So,Therefore, x = 77Percentage of =77% Then, percentage of =23% |
