In the laboratory you dissolve 24.6 g of calcium acetate in a volumetric flask and add water to a total of 250 ml. what is the m of the solution? the concentration of calcium cation? concentration of acetate anion

Ca(C2H3O2)2

mole of calcium acetate = 24.6 / (40.1 + (2* (2*12+3*1+2*16)))

=0.156 mol

molarity = mole / volume = 0.156 / ((250cm^3/1000)dm^3) = 0.624M

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.
