Mole: A mole is a unit to count atoms or molecules. When we have a mole, we are counting one Avogadro's worth {eq}\displaystyle (N_A = 6.022\ \times\ 10^{23}){/eq} of these atoms or molecules. The mole is an important quantity because it is also considered as a state function...
In other words, one water mole has a mass of 18.016 grams. Density of Water We can use the density of water to determine the mass of water per unit volume. The density of water varies depending on conditions (warm water is less dense; cold water is denser), but the value typically us...
