If At 25 Degrees C, the molar solubility of barium chromate in water is 1.1 x 10^-5 M. Here is how you would find the solubility in grams per liter.
First: You must know the molar mass of Barium Chromate To continue. Look at your Periodic Table.
[BariumChromate Molar mass=253.37 g/mol]
*Get this by adding together atomic number of each element in BaCrO4
*253.37= Ba+Cr+O(4), or 137.33+52+16(4)
*Take 1.1 x 10^-5 M and divide by molar mass of Barium Chromate
1.1 x 10^-5 mol/L x 253.37 =0.002787
Answer in grams per liter to three significant figures=2.787 x 10^-3 g/L
How many liters of water are required to dissolve 1 of barium chromate?
*take 1gram BaCrO4 / 2.787 x 10^-3 g/L --------> Grams Cancel
=2.787 x 10^-3 L
Answer in liters to three significant figures =359.71 Liters
What is the solubility of barium chromate in parts per million?
*parts per million = Grams of Solute/grams of solution X 10^6 (which is ppm)
2.787 x 10^-3g/L x 1L/1000g x 10^6 = 0.02779, or 2.78 x 10^-2ppm
Answer in parts per million to three significant figures=2.78ppm
**For dilute aqueous solutions, ppm is equivalent to units of mg/l
Chromium does not occur freely in nature. The main chromium mineral is chromite. Chromium compounds can be found in waters only in trace amounts. Many chromium compounds are relatively water insoluble. Chromium (III) compounds are water insoluble because these are largely bound to floating particles in water. Chromium (III) oxide and chromium (III) hydroxide are the only water soluble compounds.Chromium (VI) oxide is an example of an excellently water soluble chromium compounds
Solubility:
6.5% @ 10C (50F) in water.
See the Web Links to the left for the original source.
Chromium (III) hydroxide is highly soluble in distilled water but dissolves readily in either acidic or basic solution
The anhydrous chromium(III) sulfate is not soluble in water; the hydrated salt is soluble in water.

Some chromium compounds: chromium bromides, chromium chlorides, chromium fluorides, chromium iodides, potassium dichromate, sodium chromate, chromium oxide, chromium sulfide, etc.
Chromium fluorides are: Chromium difluoride: CrF2 Chromium trifluoride: CrF3 Chromium tetrafluoride: CrF4 Chromium pentafluoride: CrF5 Chromium hexafluoride: CrF6
Cr2+ is a divalent cation of chromium; ex.: chromium in chromium diiodide, CrI2.
