In chemistry, a mole is a quantity used relate reactants to products in stoichiometric equations. A mole of any substance is equal to 6.02 x 10^23 particles -- usually atoms or molecules -- of that substance. For a given element, the mass (in grams) of o

The electronic structure of the individual elements in a compound determines the formula of a compound (see page 33). The formula of an ionic compound is determined by the charges on each of the ions present. The number of positive charges is balanced by the number of negative charges so ...
What is the formula for calculating the number of moles?Question:What is the formula for calculating the number of moles?Mole:Mole is an important concept used in chemistry. It represents the amount of molecule which has the exact mass of its gram molecular mass. One mole also contains an ...
What is mole in chemistry class 9? The mole isthe amount of substance that contains the same number of particles (atoms/ ions/ molecules/ formula units etc.)as there are atoms in exactly 12 g of carbon-12. • Mass of 1 mole of a substance is called its molar mass. ...
The xx in (A3B2)x(A3B2)x is a part of the chemical formula for that compound, and not the moles of (A3B2)(A3B2) produced. For example, AlCl3AlCl3 usually exists as a dimer in gas phase, so we write it as Al2Cl6Al2Cl6 or simply (AlCl3)2(AlCl3)2 for clarity. You should...
