0.12g of an organic compound containing phosphorous gave 0.22g of Mg2P2O7 by usual analysis. calculate the percentage of phosphorous in the compound.
Asked by | 23 Feb, 2013, 08:23: PM
Expert Answer
The mass of the compd = 0.12 g
Mass of Mg2P2O7 = 0.22 g
Since 1 mole of Mg2P2O7 has 2 g atoms of P, or
222 g of Mg2P2O7 = 62 g of P
So, 0.22 g of Mg2P2O7 contains P = 62/222 x 0.22 g
So % P present in the compound = 62/222 x 0.22 x 100/ 0.12
