Question

-Calculating solubility A chemistry student weighs out 0.55 kg of an unknown solid compound X and adds it to 550. ml. of distilled water at 28. C. Alter 10 minutes of stirring, only some of the X has dissolved. The student drains off the solution, then washes, dries and weighs the X that did not dissolve. It weighs 0.44 kg. yes Using only the information above, can you calculate the solubility of X in water at 28. C If you said yes, calculate it. Be sure your answer has a unit symbol and the right pumber of significant digits

Explanation / Answer

yes,it is possible to determine solubility.

solubility = mass of X dissolve / volume of water

            = (0.55 - 0.44)*10^3 / 550

solubility(s) = 0.2 g/ml
