Question

How many moles of N2 are needed to make 5.0 moles of NH3?

Answer 1

The answer is "2.5 mole"

Step-by-step explanation:

The reaction for producing
`NH_3` can be defined as follows:

Reaction:

`N_2+ 3H_2 \rightarrow 2NH_3`

According to the above reaction, to produce 2 moles of
`NH_3` we need 1 mole of nitrogen:

So, according to the question to produce 5.0 mole
`NH_3` the required
`N_2`:

`\Rightarrow \ 5.0 \ mole \ of \ NH_3 * (1 \ mole\ of \ N_2)/(2 \ mole \ of NH_3)\\\\\Rightarrow 5.0 * (1)/(2)\\\\\Rightarrow 2.5\ mole\\`

To produce 5.0 mole
`NH_3` we need 2.5 mole
`N_2`
