To find the atomic weight of the metal in the compound, we need to use the information given about the composition of the compound and the ratio of metal atoms to nitrogen atoms in the compound.

Let's assume the compound has a total weight of 100 grams. This means that the compound contains 28 grams of nitrogen and 72 grams of the metal.

- **Step 1: Calculate the moles of nitrogen:**
To calculate the moles of nitrogen, we need to divide the mass of nitrogen by its molar mass. The molar mass of nitrogen is 14 grams/mol.
Moles of nitrogen = mass of nitrogen / molar mass of nitrogen
Moles of nitrogen = 28 grams / 14 grams/mol
Moles of nitrogen = 2 moles

- **Step 2: Calculate the moles of the metal:**
To calculate the moles of the metal, we need to divide the mass of the metal by its molar mass. Let's assume the molar mass of the metal is M grams/mol.
Moles of metal = mass of metal / molar mass of metal
Moles of metal = 72 grams / M grams/mol
Moles of metal = 72/M moles

- **Step 3: Use the ratio of metal atoms to nitrogen atoms:**
According to the given information, 3 atoms of the metal combine with 2 atoms of nitrogen. This means that the ratio of metal atoms to nitrogen atoms is 3:2.
Moles of metal / Moles of nitrogen = 3/2
(72/M) / 2 = 3/2
72/M = 3
M = 72/3
M = 24 grams/mol

Therefore, the atomic weight of the metal in the compound is 24 grams/mol, which corresponds to option A.
