So we know that this amount of atoms is Avogadro's number - the number of atoms in 1 mole of a substance.
So then, using dimensional analysis, we can find the mass, in grams, of potassium.
First we must find the molar weight of potassium as found on the periodic table: 39.098g/mol
Then we can solve directly for mass:
Therefore, the amount of atoms you have given, in terms of mass, will equal 39.098g - if the answer requires significant figures, then the mass would be 39.1g of potassium.

When an ion is formed, the number of protons does not change. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged. A neutral chlorine atom, for example, contains 17 protons and 17 electrons
The volume of the base should be gradually increased, stopping once the equivalence point is achieved. At the volume halfway between the equivalence point and the acid, the acid's pKa is equal to the pH.
<h3>What is titration, for instance?</h3>
Titration, sometimes referred to as titrimetry, is a method for calculating the concentration of a specific analyte in a mixture that is used in chemical qualitative analysis. Titration, which is also sometimes referred to as volumetric analysis, is a crucial analytical chemistry method.
<h3>What governs titration in its basic form?</h3>
The following is the fundamental titration principle: The sample being studied is given a solution, referred to as a titrant or standard solution. A chemical is present in the titrant in a known concentration.
