Sentence examples for molecules per formula from inspiring English sources
There are 6.5 lattice water molecules per formula unit, some of which are disordered.
The salt content of the crystals was found by elementary thermogravimetry, after drying at ∼ 673 K for 24 h, to be 49.7 wt % MgSeO4 (mean of six independent determinations), which corresponds to 9.4 water molecules per formula unit.
Its water adsorption isotherm at room temperature and pressure shows that the water content in it was 31 cm3 g−1 at the maximum allowable humidity, corresponding to 3.7 water molecules per unit formula.
Additionally, a possible rationale could build on the study of Gale and coworkers who found that amorphous CaCO3 incorporates an increasing number of water molecules per CaCO3 formula unit with increasing aggregate size.[ 22] This implies an increasing degree of immobilized water molecules, giving rise to entropic disfavoring.
