Chapter 3, Problem 23QAP
Interpretation Introduction

Interpretation:

The molarity of KOH in solution II should be calculated.

Concept introduction:

The number of moles of a substance is related to mass and molar mass as follows:

n=mM

Here, m is mass and M is molar mass of the substance.

Also, according to Avogadro’s law in 1 mol of a substance there are 6.023×1023 units of that substance. Here, 6.023×1023 is known as Avogadro’s number and denoted by symbol NA.

The molarity of a solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows:

M=nV

Here, n is number of moles of solute and V is volume of solution in L. Thus, the unit of molarity is mol/L.
