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\ \%

Which pair of formulas represents the empirical formula and the molecular formula of a compound?
AnnyKZ [126]

Answer:

CH2O and C6H12O6

Explanation:

To find an empirical formula, take a molecular formula and divide the subscript of each element by the greatest common factor of all the subscripts. In this case, the only pair that works is CH2O,C6H12O6, which can be verified by dividing the coefficients of the molecular formula by 6.
