Final answer:
The substance 3N2 consists of 3 molecules, which contain a total of 6 nitrogen atoms.
Step-by-step explanation:
In the molecular formula 3N2, the coefficient indicates the number of molecules, and the subscript represents the number of atoms in each molecule. Therefore, the given substance contains 3 molecules of nitrogen (N2). As nitrogen is a diatomic molecule (N2), these 3 molecules are made up of 6 nitrogen atoms in total.
In the substance 3N₂, there are 3 molecules of N₂ and 6 nitrogen atoms.
The substance N2 refers to a diatomic molecule containing two nitrogen atoms. So, for 3N2, there are 3 molecules of N2. In total, the number of atoms in 3N2 would be 3 x 2 = 6 nitrogen atoms.
