A mole of a substance is 6.022X1023 atoms, molecules, or formula units of a substance.
What the abbreviation of amount of a substance?
mole
1 mole of Pb atom is6.023x10?
1 mole of any substance has 6.022 x 1023 atoms or molecules of that substance
Molar is the total combined mass of a mole of a substance?

What does the latent heat of vaporization represent?
The amount of energy required to turn a mole of a liquid into a gas
What does latent heat of fusion represents?
The amount of heat energy required to solid substance solid into a liquid state without any changes in temperature ______________________ Apex: The amount of energy required to turn a mole of a solid into a liquid
The amount of energy required to remove one mole of electrons from one mole of sodium atoms is the?
ionization energy
1 mole is how many joules?
The mole is a unit of quantity of matter, whereas the Joule is a unit of energy. The relation depends on the substance, and what you wish to do with it. If you had a single mole of one substance and a mole of another and they were stoichiometrically combined, then the energy from the reaction could be calculated, and that could be expressed in Joules. On the other hand, you could also use the equation E=mc2 to derive the annihilation energy of one mole of a given substance. It can be stated, therefore, that there is no trivial conversion.
What is 1st ionisation enthalpy?
it is the energy required for a mole of atom to loose a mole of electron.
What does the latent heat of fusion represent?
The energy required to melt a substance. (Apex)
What is the name given to the energy required to separate one mole of the ions of an ionic compound?
Lattice Energy
Why matters which have vapor pressure do not just boil away as vapors when placed in vacuum?
Well they do -- but it takes time and energy. In order for a substance to go from a solid or liquid state to a gaseous state requires a certain 'heat of evaporation' measured in joules per mole. If this heat is provided then the substance will vapourize completely.
What is the definition for latent heat of melting?
The amount of heat released / absorbed from a substance at constant temperature as you change state from liquid->solid / solid->liquid.
