Question

A 3.1 M solution contains 3.1 _________ of solute dissolved in 1 _________ of solution.
The M in 3.1 M refers to _________.
The concentration of a 3.1 M solution may also be expressed as _________ and would be expressed in _________.​

Answer 1

Answer:

A 3.1 M solution contains 3.1 moles of solute dissolved in 1 liter of solution.

The M in 3.1 M refers to molarity. The concentration of a 3.1 M solution may also be expressed as normality and would be expressed in N

Explanation:

Molarity means, the moles of solute dissolved in 1 L of solution.

Normality means the equivalent weights per liter of solution.

How can you obtein the equivalent weights?

You have to know the molar mass of your compound and then divide between n, where n can be the valencia state of a compound, the electrons or protons transfer in reactions or, the number of H+ or OH- that a molecule transfer.

Equivalent weights = Molar mass / n

Answer 2

The term molarity refers to the number of moles that is dissolved in one litre of the solution.

What is molar concentration?

The term molar concentration shows the amount of solute that is contained in 1 L of solution. Hence, when we say that this is 3.1 M solution, we mean that there are 3.1 moles of the solute in 1 L of the solution.

We can also express this as 3.1 Mol/L and this is alsocalled the molarity of the solution.
