FIRST FIND MILI GRAM EQUIVALENT MOLECULAR WEIGHT OF CALCIUM CHLORIDE FROM ITS FORMULA ..THERE IS 1 TOM OF CALCIUM AND 2 ATOMS OF CHLORINE IN IT.HENCE M.WT. =1*CA+2*CL=1*40+2*35.5=111...SO
IN 111 MG OF CACL2 WE HAVE 40 MG.EQV. OF CALCIUM
IN 250 MG OF CACL2 WE SHALL HAVE 250*40/111=90 MG.APPROXIMATELY
