Question

How would a solution that is labeled 5.0 M would be read as?

5.0 molar
5.0 moles
5.0 concentrated
5.0 dilute

Answer 1

5 moles because molarity signifies number of moles dissolved in One litre of water

Answer 2

Answer: Option (a) is the correct answer.

Step-by-step explanation:

It is known that molarity is the number of moles of a substance present in liter of a solution.

Mathematically, Molarity =
`\frac{\text{no. of moles}}{\text{volume in liter}}`

Symbol which represents molarity is "M". For example, a solution of 5.0 M means that molarity of the solution is 5.0 or the solution is 5.0 molar.

Thus, we can conclude that a solution that is labeled 5.0 M would be read as 5.0 molar.
