Answer is: <span>2 molar, but 2 moles of a solute in 1 liter of solution.
</span>This is molar concentration<span> (c) or </span>molarity and it<span> is a measure of the </span>concentration<span> of a </span>solute <span>in a </span>solution.
<span>Unit for molarity (c = n/V) is the number of </span>moles (n)<span> per </span>litre (V)<span>, having the unit symbol mol/L or sometimes mol/dm</span>³.
Answer: d
explanation: only eukaryotic cells contain a nucleus. inside the nucleus is dna/chromosomes
Electrons cannot be located between levels except when they are in the process of moving.
The limitation of the maximum number of electrons in a given energy level can be used to account for the periodic recurrence of properties as the number of electrons increases.
Explanation:
- The Bohr's model of the atom is based on quantum mechanics.
- He suggested that electrons are contained in specific spherical orbits around the nucleus.
- The orbits are also known as shells or energy levels.
- The maximum number of electrons that can be contained by an energy level is 2n².
- An electron in an energy level has a definite amount of energy associated with it at that level.
- Electrons can undergo transitions from one level to another.
