Answer:
Mass of pendulum bob is the correct answer.
Explanation:
There are different kinds of compositions. The percentage mass composition of chlorine is 42% in HClO3 (gram-formula mass = 84 g/mol)
<h3>What is HClO3 known as?</h3>
This HClO3 is known to be popularly called as Chloric acid.
Percentage mass of chlorine is formula:
Percentage mass composition = mass of element * 100%/mass of compound.
