The fullest correct name is monoaluminum trifluoride. It is often called more simply aluminum trifluoride, or even aluminum fluoride.
Examples are: AlF3, (NH4)2PtCl6, NH4HC4H4O6, (NH4)2C2O4, Ba(BrO3)2.H2O, BaHPO3 etc.
molar mass of AlF3 = 83.9767 g/molmolality = moles solute per kg solventmoles solute = 131 g x 1 mol/83.9767 g = 1.56 moleskg solvent = 3.60 kgMOLALITY = 1.56 moles/3.60 kg = 0.433 m (3 significant figures)
A solid.
Yes. Most metal to non-metal combinations are crystalline solids. The formula for aluminum fluoride is AlF3.
Formula: AlF3
molar mass AlF3 = 83.98 g/mole33.4 g AlF3 x 1 mole/83.98 g = 0.398 molesEach mole of AlF3 contains 3 moles of F- anions, because AlF3 ==> Al^3+ + 3F^-.Thus, moles of anions = 3 x 0.398 = 1.19 moles of anions
The first symbol represnts the compound magnesium iodide (MgI2) and the second symbol represents aluminum fluoride (AlF3)
AlF3
aluminum fluorite
Al(FlO3)3. Al has a charge of +3 and FlO3 has a charge of -1 so 3 fluorate ions are needed for every Al ion to balance the charge of the compound. ***extra--if you didn't know what fluorate was.... A well known ion, ClO3 (the chlorate ion), has a charge of -1. Fl is in the same group as Cl so the fluorate ion will have the same number of oxygens and the same charge as ClO3.
Solid aluminium trifluoride has a three dimensional structure which is surprisingly not well understood. It is probaly mainly ionic. AlF3 in the gas phase is covalent with a planar structure.
Formula: AlF3
