Question
Chapter 6.5, Problem 6.4QC
Interpretation Introduction
Interpretation:
The objective is to find the molarity of KSCN solution obtained by dissolving 0.440 g of KSCN in enough water to make 340. mL of solution.
Concept Introduction:
Molarity of a solution is defined as the amount of solute dissolve in 1 L of solution.
It is mathematically represented as follows:
Here, n is number of moles of solute and v is volume of solution is L.
Also, number of moles are related to mass and molar mass as follows:
Here, m is mass and m is molar mass.
