Final answer:
To calculate the number of molecules in 100.0 grams of Ammonium phosphide, we need to convert grams to moles and then moles to molecules.
Step-by-step explanation:
The number of molecules contained in a given amount of a substance can be calculated using Avogadro's number. Ammonium phosphide (NH4)3P is a compound consisting of three ammonium ions (NH4+) and one phosphide ion (P3-). To calculate the number of molecules in 100.0 grams of Ammonium phosphide, we need to convert grams to moles and then moles to molecules. First, we find the molar mass of (NH4)3P, which is 85.09 g/mol. Then, using the formula:
Number of moles = mass / molar mass
We can calculate the number of moles of (NH4)3P. Finally, we can multiply the number of moles by Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of molecules in 100.0 grams of Ammonium phosphide.
