Asample of 30.00 grams of potassium phosphate was added to a solution containing 100.0 ml of 0.25 m calcium nitrate. calcium phosphate was precipitated according to the following reaction. 2k3po4(s) + 3ca(no3)2(aq) - ca3(po4)2(s) + 6kno3(aq) 2.25 grams of calcium phosphate were recovered. calculate the theoretical yield and the percent yield.

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
