Gravimetric analysis - worked example
A gravimetric analysis to determine the percentage, by mass, of phosphorus
in a sample of fertiliser involved treating the sample to convert the
phosphorus into the insoluble compound magnesium pyrophosphate Mg2P2O7.
In a particular analysis, a 2.294 g sample of the fertiliser produced
1.437 g of Mg2P2O7. Calculate the percentage, by mass, of phosphorus in the
This is a question where considering the final stage of the calculation
helps simplify the question.
