What is mole? How to calculate the number of moles?Mole:Atoms and molecules are extremely small objects. Even a few grams of a substance contains an unimaginably large number of atoms and molecules. The Mole is a unit that is used to count the number of these objects....
The mole is one of the more important concepts in chemistry. In technical terms a mole consists of 6.022 x 1023molecules of a substance. In more practical terms a mole is the number of molecules necessary to have an amount of substance in grams equal to the substance’s molecular weight in...

How to Calculate Particle Concentration. The particle concentration within a solution describes the number of particles dissolved in the solvent. A solution may contain billions upon billions of particles, so chemists, for convenience, specify the amount
Chemistry is full of many different confusing conversions. These conversions are important because they ultimately allow us to discover how a particular atom or molecule will interact with other atoms and molecules. Central to chemical conversions is the conversion of grams to moles, and vice versa....
Divide the number of moles of weak acid molecule (from Step 1) by the total volume of the buffer solution (from Step 5). This gives you [HA], the concentration of the weak acid in the buffer. Step 7 Divide the number of moles of conjugate base salt molecules (from Step 3) by the...
Calculate the molarityof a solution prepared by dissolving 23.7 grams of KMnO4into enough water to make 750 mL of solution. This example has neither the moles nor liters needed tofind molarity, so you must find the number ofmolesof thesolutefirst. ...
Calculate the number of copper ions per gram of copper from the number of copper ions above and the mass of copper ions produced. The mass of the copper ions produced is equal to the mass loss of the anode. (The mass of the electrons is so small as to be negligible, so the mass of...
