1.	0.515 g of an organic compound containing phosphorus gave 0.214 g of magnesium pyrophosphate in Carius method for the estimation of phosphorus. Calculate the percentage of phosphorus in the given organic compound.
Answer» <P> Solution :MASS of organic compound `=0.515 g` Mass of MAGNESIUM pyrophosphate, `Mg_(2)P_(2)O_(7)=0.214 g` `{:(Mg_(2)P_(2)O_(7),equiv,2P),(22g,,62g):}` 222g of `Mg_(2)P_(2)O_(7)` are obtained from PHOSPHORUS `=62 g` 0.214 g of `Mg_(2)P_(2)O_(7)` are obtained from phosphorus `=(62xx0.214)/222=0.0597 g` Percentage of phosphorus `=("Mass of phosphorus")/("Mass of organic compound")xx100=(0.0597xx100)/0.515=11.6`.
