What is meant by the term 1 mole?
A mole is the amount (10) of material containing 6.02214 × 1023 particles. 1 mol = 6.02214 × 1023 particles. This number is also called Avogadro’s number… Notice that the definition of the mole is an amount of substance.
What is meant by the term mole reaction?
One mole of reaction (molrxn) refers to a reaction unit. In order to define a mole of reaction the chemical equation must be known. For a chemical reaction, the change in moles for each species is tied to molrxn by the stoichiometric coefficient.
What is the mole of calcium?
The Molar Mass of Calcium The number under the symbol for calcium, Ca, tells you the molar mass of the element. This is the number of grams in 1 mole of calcium. The mass of 1 mole of calcium is 40.078 grams.
What is mole fraction in chemistry class 11?
Mole fraction is equivalent to the ratio of moles of a specific component to the number of moles of solution. The mole fraction is the ratio of the number of moles of one component to the total number of moles of the solution (i.e., all the components).
What is a mole in chemistry GCSE?
The mole is the unit for amount of substance. It is abbreviated to mol. 1 mol is the amount of substance that contains the same number of particles as there are atoms in 12.0 g of carbon-12.
Which best defines what a mole represents in chemistry?
