Interpretation: To determine the molar mass of ammonium phosphate.
Concept Introduction: The mass in grams of one mole of a compound is known as its molar mass. The unit for molar mass is g/mol, or grams per mole.
Answer to Problem 2STP
The molar mass of ammonium phosphate will be 149 g/mol.
Explanation of Solution
The molecular formula of ammonium phosphate =
The molar mass of Nitrogen = 14 g/mol =
The molar mass of hydrogen =
The molar mass of phosphorus = 31 g/mol
The molar mass of oxygen =
By adding the molar mass of nitrogen, hydrogen, phosphorous, and oxygen
Therefore, the molar mass of ammonium phosphate will be 149 grams/mol.
