Naturally occurring chlorine that is put in pools is 75.53 percent 35cl and 24.47 percent cl. calculate the average atomic mass.

Based on the data provided, the relative atomic mass of naturally occurring chlorine that is put in pools is 75.53 percent 35Cl and 24.47 percent 37Cl is 35.5

Relative atomic mass of an element is calculated using the formula below;

Relative atomic of chlorine = 35 × 75.53 + 37 × 24.47

Relative atomic mass of chlorine = 35.5

Therefore, the relative atomic mass of naturally occurring chlorine that is put in pools is 75.53 percent 35Cl and 24.47 percent 37Cl is 35.5.
