Explanation:
using Boyles law: which shows the relationship between pressure and volume, when temperature Is kept constant
P1V1 = P2V2
2 x 7.2 = 0.5 x V2
14.4 = 0.5 x V2
V2 = 14.4/0.5 = 28.8 L
Hence the new size of the balloon in litres is 28.8
Boyle's Law states: pV = constant.
24.43 x 1.895 = 46.29485
therefore, 15.6 x _____ = 46.29485
unknown = 2.968L
The molecular compound in the given statement is CH₆N₂.
<h3>What defines a molecular compound?</h3>
Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.
<h3>Briefing:</h3>
Consider 140.22 g/mol of compound
Carbon = 140.22 * 51.38/100
Carbon = 72 gm = 1 mol
Hydrogen = 140.22 * 8.64/100
Hydrogen = 12 gm = 6 mol
Nitrogen = 140.22 * 39.97/100
Nitrogen = 56 gm = 2 mol
The molecular compound is CH₆N₂.
