Answer 1

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
`(mol)/(L)` and would be expressed in
`(mol)/(dm^(3) )`

Step-by-step explanation:

The molarity reflects the concentration of a solution indicating the amount of moles of solute that appear dissolved in each liter of the solution.

`M=(solute moles)/(solution volume)`

Although various units can be used, it is usual to use
`(mol)/(L)`, equivalent to
`(mol)/(dm^(3) )`. This unit is usually expressed as a molar, with an M as a symbol.
