It can be expressed as the mass of the solute per unit volume or the number of moles of solute per unit volume. A mole of any substance is Avogadro's number of particles. The relationship among concentration, amount of solute, and volume of solution can be used to determine the volume ...
When an electron is transferred from one element to another, how does the element getting an extra electron still become a positive ion? Is the atom the smallest part of matter? If electrons are leptons, and leptons, along with quarks, are fermions, then how are electrons mad...
