The correct answer is:
\(51.20 \%\)
Estimation of phosphorus in organic compound is down by using magnesia mixture. It uses the working formula.
\(\mathrm{P} \%=\frac{62}{222} \times \frac{w_1}{w} \times 100=\frac{62}{222} \times \frac{0.22}{0.12} \times 100=51.20 \%\)
\(\mathrm{P} \%=\frac{62}{222} \times \frac{w_1}{w} \times 100=\frac{62}{222} \times \frac{0.22}{0.12} \times 100=51.20 \%\)
