Rubidium Sulfide | AMERICAN ELEMENTS
Rubidium Sulfide is a moderately water and acid soluble Rubidium source for uses compatible with sulfates.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.

The heavier alkali metals (rubidium and cesium) will spontaneously ignite upon exposure to air at room temperature. Alkali metals react with water to produce heat, hydrogen gas, and the corresponding metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion.
Grams to Moles Calculator
How to calculate moles from grams? - Grams to moles formula. To correctly estimate the number of moles, n, of a substance of a specific mass, m, (in grams), you need to follow the grams to moles formula: n = m / M,. where, M is the molar mass of this material. The unit is typically g/mol.; But wait, what actually is a mole?
