Pure water molar mass
WebSolution. To use Raoult's Law (Equation 1 ), we need to calculate the mole fraction of water (the solvent) in this salt-water solution. χsolvent = moles of water moles of solute + moles … WebWater has several important physical properties. Although these properties are familiar because of the omnipresence of water, most of the physical properties of water are quite atypical. Given the low molar mass of its constituent molecules, water has unusually large values of viscosity, surface tension, heat of vaporization, and entropy of vaporization, all …

Molar mass is closely related to the relative molar mass (Mr) of a compound, to the older term formula weight (F.W.), and to the standard atomic masses of its constituent elements. However, it should be distinguished from the molecular mass (which is confusingly also sometimes known as molecular weight), which is the mass of one molecule (of any single isotopic composition) and is not directly related to the atomic mass, the mass of one atom (of any single isotope).
