What is the chemical formula formula for rubidium carbonate?
Rb2CO3 for rubidium carbonate
A 6.88 g sample of the hydrated crystal Rb2CO3 xH2O is heated until all the water is removed The remaining solid weighs 5.24 g Calculate the formula of the hydrated crystal?
Okay, the anhydrate that weighs 5.24g (after heating) is pure rubidium carbonate (Rb2CO3) so the 6.88g represents the molar mass of the hydrated crystal. Set up an algebraic direct proportion: 6.88/x = 5.24/(molar mass of Rb2CO3) which is 231g/mol. Solve for x to get 303.3. Subtract out the anhydrate mass: 303.3 - 231 = 72.3. Now divide that number by water's molar mass, which is 18g/mol: 72.3/18 = 4, so the formula of the hydrate crystal is Rb2CO3-4H2O.
