PV = nRT
1.026atm * 42l = n * 0.0821L atm/mol K * 305K
n=1.72.
1.72 molecules.
Answer:
Draw the skeletal structure for: (E)-hept-5-en-2-one
Explanation:
The root word hept indicates that the given compound has seven carons in its longest chain.
-en- primary suffix indicates that the compound has one double bond in it.
2-one indicates that the compound has -C=O bond in the second carbon.
The prefix (E) indicates that the highest priority groups are on the opposite direction of the double bond.
The structure of the given molecule is:
In aqueous solutions, the hydrogen ion, also known as the hydronium ion, is a Bronsted-Lowry acid, while the hydroxide ion is a base as a result of the self-dissociation reaction.

Brønsted–Lowry acid-base theory:</h3>
Any species that may transfer a proton (H+) to another molecule is a Brnsted-Lowry acid. Any species that can take a proton from another molecule is a Brnsted-Lowry base. In essence, a Brnsted-Lowry base is a proton acceptor (PA) and an acid is a proton donor (PD).
According to the Arrhenius theory, acids are defined as chemicals that dissociate in an aqueous solution to produce hydrogen ions (H+), whereas bases are defined as substances that produce OH (hydroxide ions).
The hydrogen ion, or hydronium ion, is a Brønsted–Lowry acid in aqueous solutions, and the hydroxide ion is a base, by virtue of the self-dissociation reaction.
