How many moles of DAP,(NH4)2HPO4 are there in 26.2g of DAP

Moles of  diammonium phosphate = 0.2 mol

Explanation:

Given data:

Mass of diammonium phosphate = 26.2 g

Moles of  diammonium phosphate = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of  diammonium phosphate is 132.06 g/mol

Number of moles = 26.2 g/ 132.06 g/mol

Number of moles = 0.2 mol

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
