Question

Calculate the relative atomic mass of this sample of chlorine. Two decimal places.

Answer 1

Step-by-step 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

`\begin{gathered} \text{ Relative atomic mass = }\frac{\text{ 75.53 }*\text{ 35}}{100} \\ \text{ } \\ \text{ Relative atomic mass = }\frac{\text{ 2643.55}}{\text{ 100}} \\ \text{ Relative atomic mass = 26.44} \end{gathered}`

Therefore, the relative atomic mass is 26.44
