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 is useful whether or not we know how many atoms of carbon 12 there are in 12 000 g of carbon 12 if we weigh one mole of iron and one mole of sulfur we know that these two samples contain the same number of atomsthis is the important aspect of the mole how many atoms there are in a mole is of subsidiary importancenonetheless it has become possible to determine this number it is of course 6 022 x 1023 atoms per mole we thus see that this number is simply a consequence of the choice that 1 mole be the formula weight in gramshe mole is the same kind of unit as the dozen a certain number of things but it differs from the dozen in a couple of ways first the number of things in a mole is so huge that we cannot identify with it in the way that we can identify with 12 things
