Question

How many nitrogen atoms are in one molecule of the compound Al(NH3)2?

Answer 1

2.
Similarly to algebra, anything in parentheses that has a number following it with no sign is multiplied by that number. So if you were to ask for the H, H would be 6.

Answer 2

There are two numbers of nitrogen atom in the given molecule.

Step-by-step explanation:

In given molecule,
`Al(NH_3)_2` is made up of aluminum, nitrogen and oxygen atoms.

Number of nitrogen atoms in the molecule.:
`1* 2= 2`

Number of hydrogen atom in the molecule =
`3* 2= 6`

Number of Aluminum atom in the molecule=
`1* 1= 1`
