What is meant by moles?
- In chemistry, a mole, sometimes spelled mol, is a common scientific measurement unit for significant amounts of very small objects like atoms, molecules, or other predetermined particles. The mole designates 6.02214076 1023 units, which is a very large number. The International System of Units uses the mole (symbol: mol) as the unit of material quantity.
- How many elementary entities of a particular substance are present in an object or sample is determined by the quantity of that material. It is specified that the mole contains exactly 6.022140761023 elementary entities. The term "mole" refers to an extremely large quantity of molecules, atoms, or other particles and is used as a unit of measurement in chemistry.
Molar Concentration = number of moles/ volume
volume = number of moles/ molar concentration
volume = 0.2150/ 0.3000 = 0.71 L
volume required = 0.71 L = 0.71L× 1000 mL/L = 710 mL
