Answer: If it was 3 mol of solute in 2 L of solution it would be 1.5 mol/L.
However when the solute dissolves in the water creating the solution, the volume increases. So 3 mol of solute in 2 L of water creates more than 2 L of solution.
The correct method for making a 3 mol/L solution would be to place some water into a two liter volume container. Dissolve all 3 mol of the solute into the water. Then add water to the 2 L mark. Now there is 3 mol of solute and 2 L of solution.

Answer:
hello your question is incomplete below is the missing question
what is the PH
answer : 13
Explanation:
The PH of 0.1M solution of the salt Na = 13
attached below is a detailed solution
Because the decomposition is the reverse process of the formation.
Enthalpy is a function of state, which means that the value dependes only on the state and not the pathway.
Then the change of enthalpy is the same in magnitude for both cases but in formation the change is netavie (releases energy) and in the other is postive (absorbs energy).
The ion formed is known as the bromate ion, and it has a chemical formula BrO₃⁻
The bromate ion has two oxygen atoms that have formed two covalent bonds with the bromine atom and one oxygen atom has a single covalent bond with the bromine, yielding an overall charge of -1. The bromine ion is exhibiting a charge of +7, while the oxygen ions are exhibiting a charge of -2.
