Calculate the mass (g) of solid potassium carbonate (K2CO3) needed to prepare 50 mL of a 1.0 M potassium carbonate solution. (This is the 1.0 M K2CO3 solution that you will use in your pigment synthesis.) There are several ways to approach this. Perhaps the easiest is to first determine the moles of K2CO3 in 50 mL of 1.0 M K2CO3 solution and then calculate the mass (g) of K2CO3 that corresponds to the moles.

Dumbledore decides to gives a surprise demonstration. he starts with a hydrate of na2co3 which has a mass of 4.31 g before heating. after he heats it he finds the mass of the anhydrous compound is found to be 3.22 g. he asks everyone in class to determine the integer x in the hydrate: na2co3·xh2o; you should do this also. round your answer to the nearest integ
