ANSWER
EXPLANATION
Given that;
The atomic mass of chlorine = 35
The % of the sample in chlorine atom = 75.53%
Relative atomic mass is a physical quantity that define the ratio of the average mass of atoms of a chemical in a given sample to the atomic mass constant.
The next step is to find the relative atomic mass of the sample
[tex]\begin{gathered} \text{ Relative atomic mass = }\frac{\text{ 75.53 }\times\text{ 35}}{100} \\ \text{ } \\ \text{ Relative atomic mass = }\frac{\text{ 2643.55}}{\text{ 100}} \\ \text{ Relative atomic mass = 26.44} \end{gathered}[/tex]
Therefore, the relative atomic mass is 26.44
