The state's landlord-tenant laws protect people living in dwellings owned or leased by others. A person need not be listed on a formal lease to gain protection under these laws, but may gain protection by establishing residence in a place.
The mole is useful in chemistry because it is defined such that the mass of Avogadro's number of particles (atoms or molecules) of a substance (the molar mass) is equal to the sum of the numerical values of the atomic masses of its constituent elements.
The mole (abbreviation, mol) is the Standard International ( SI ) unit of material quantity. One mole is the number of atom s in precisely 12 thousandths of a kilogram (0.012 kg) of C-12, the most common naturally-occurring isotope of the element carbon. This number is equal to approximately 6.022169 x 10 23 , and is also called the Avogadro constant. The mole is the only fundamental SI unit that is dimensionless. That means it represents a simple numerical quantity or value; it is a term similar in nature to dozen (meaning 12) or gross (meaning 144). But 1 mol is, unlike a dozen or a gross, an incomprehensibly large number.
