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.
Therefore;
HClO3 (gram-formula mass = 84 g/mol)
Percentage mass composition of chlorine = 35 * 100% / 84 = 42%
See full question below.
In which compound is the percent composition by mass of chlorine equal to 42%?
(1) HClO (gram-formula mass = 52 g/mol)
(2) HClO2 (gram-formula mass = 68 g/mol)
(3) HClO3 (gram-formula mass = 84 g/mol)
(4) HClO4 (gram-formula mass = 100. g/mol)

If you draw line segments DF and FG, you can show ΔDEF ≅ ΔGEF by SSS (side-side-side congruence). So, ∠DEF ≅ ∠GEF because corresponding parts of congruent triangles are congruent. Have fun with.. life lol
Bromine has stronger inter molecular force than Fluorine.
<h3> Inter molecular forces and relationship with physical states of matter</h3>
The intermolecular forces of a substance tells the physical state of that substance , We can therefore say that the Solid, liquid and gas states of substances depends on the intermolecular forces surrounding them.
- For solids,the inte molecular forces will be so strong as they draw the molecules together giving them a compact structure.
- For liquids, the the inter molecular forces will be just strong enough to keep the molecules together in a confined space.
- For gases, the the inter molecular forces are weakest as the molecules move about.
We can then conclude that At stp, fluorine is a gas and bromine is a liquid because, compared to fluorine, bromine has a stronger intermoleclar force.
