(GREEN) moles I solids
how do you calculate moles in a solid
n = mass/RMM
what is the definition of atom
An atom is the smallest uncharged particle of an element
what is the definition of element
An element is a substance that cannot be broken down into two or more different substances
what is the definition of compound
A compound is made up of two or more elements chemically joined together
what is the definition of ion
An ion is a charged atom or group of atoms
what is the definition of mole
A mole is the amount of substance containing the Avogadro number of atoms, molecules or groups of ions. Where Avogadro’s number is 6.023 1023 mol-1.
what is the definition of empirical formula
The empirical formula of a substance is the simplest whole number ratio of the atoms of each element in the substance
what is the definition of molecular formula
The molecular formula of a compound shows the number of atoms of each element in one mole of the substance.
what is the definition of Parts per million
Parts per million is the mass of solute per million grams of solvent.
what is the definition of The relative atomic mass
The relative atomic mass of an element is the weighted average mass of the atoms of an element in their natural isotopic abundance compared to the carbon-12 isotope taking
12C = 12.0000.
what is the definition of The relative molar mass
The relative molar mass in grams of any molecule contains the same number of molecules as there are atoms of carbon in 12g of carbon-12.
what is the definition of avagadros constant
The Avogadro Constant is the number of atoms in exactly 12g of 12C which is 6.02
