MgNH4PO4•6H2O loses H2O in a stepwise fashion as it is heated. Between 40 degrees celsius and 60 degrees celsius, the monohydrat
tino4ka555 [31]

Answer:

\%\ Composition\ of\ phosphorus=20.00\ \%

Explanation:

The molecular formula of the monohydrate formed = MgNH_4PO_4.H_2O

The molecular mass of the monohydrate formed = Mass_{Mg}+Mass_{N}+6\times Mass_{H}+5\times Mass_O

So, Mass = 24 + 14 + 6 × 1 + 5 × 16 = 155 g

Mass of phosphorus = 31 g

Thus,

\%\ Composition\ of\ phosphorus =\frac{Mass_{phosphorus}}{Total\ mass}\times 100

\%\ Composition\ of\ phosphorus=\frac{31}{155}\times 100

\%\ Composition\ of\ phosphorus=20.00\ \%

Describe the difference beetween an extensive and intesive property
olasank [31]

Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
