WebApr 23, 2024 · The standard molar entropy is directly proportional to molar mass hence He(g) has the lowest standard molar entropy.. The entropy of a substance refers to the degree of disorderliness of a substance.Usually, gases are more disorderly than liquids and liquids are more disorderly than gases. This means that a gas has the highest degree of … WebThe mole was defined in such a way that the molar mass of a compound, in g/mol, is numerically equal to the average mass of one molecule, in daltons. It was exactly equal before the redefinition of the mole in 2024, and is now only approximately equal, but the difference is negligible for all practical purposes. WebThe weight of the CaSO 4 alone is 136.139 g. The weight of one-half mole of water is 18.015 x 0.5 = 9.0075 g.
