What is the concentration of a solution in terms of solute per liter of solution
🔄 Click to see definition
Definition1/18
The molarity of a solution is the number of moles of a solute
per liter of its solution.
The normality of a solution is the number of gram equivalent
weight of a solute per liter of its solution.
As I said before, and precisely, Molarity is moles of solute per
VOLUME of solution!

When does molarity and molality become equal
🔄 Click to see definition
Definition1/18
In dilute solutions... ie closer a solution is to pure water the
closer molality and molarity come to equalling each other. This is
because the molality uses mass and molarity uses volume, the ratio
of these two (mass and volume) is density, and water has the
density of 1 therefore the mass and volume are equal to each other.
THEREFORE calculating the molarity of water is the same as
calculating the molality of water.

Definition1/18
Digits after (to the right of) the decimal point contribute to the accuracy of the number, not its magnitude (or size). So only the digits to the left of the decimal point contribute to the magnitude.
