Ammonia molecules have three hydrogen atoms and one nitrogen atom. how many of each atom arein five molecules of ammonia

Now 1 mole of ammonia also contains 6.022 * 10^23 molecules of ammonia. In one molecule of ammonia,we have 1 nitrogen atom and 3 hydrogen atom. Hence a total of 4 atoms, so in 6.022 * 10^23 molecules of ammonia we will have 4 * 6.022 * 10^23 number of atoms.

Step-by-step explanation:

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18
