Step 1

Step 1: The molarity of a solution is given by the formula $M_1V_1 = M_2V_2$, where $M_1$ is the initial molarity, $V_1$ is the initial volume, $M_2$ is the final molarity, and $V_2$ is the final volume. Show more…

Key Concepts

Molarity

Molarity is a measure of concentration defined as the number of moles of solute per liter of solution. It quantifies how many moles of a substance are dissolved in a given volume, making it a crucial concept for preparing and diluting solutions in chemistry.

Conservation of Moles in Dilution

In a dilution process, the amount of solute remains constant even though the total volume changes. This principle is mathematically represented by the equation M1V1 = M2V2, where M1 and V1 are the initial molarity and volume, and M2 and V2 are the final molarity and volume, respectively. It is essential for calculating the new concentration after dilution.
