The percentage of in is .
Further explanation:
Molar mass:
The molar mass of a compound is the summation of masses of all atoms or molecule present in the 1 mole of compound. In other words, Molar mass of a compound is the ratio of mass of compound in grams to the number of moles present of that compound. The S.I unit of molar mass is gram per mol or g/mol.
Step 1: The molar mass of is calculated as follows:
…… (1)
The atomic mass of Mg is 24.305 g.
The atomic mass of P is 30.974 g.
The atomic mass of O is 16 g.
Substitute these values in equation (1).
Step 2: The molar mass of is calculated as follows:
…… (2)
The atomic mass of P is 30.974 g.
The atomic mass of O is 16 g.
Substitute these values in equation (2).
The reaction of formation of is as follows:
The percentage of incan be calculated as follows:
