Moles!!!

The formula for the production of ammonia in the haber process is as follows:
N2 + 3H2 ----> 2NH3

Molar mass
Nitrogen = 28
Hydrogen = 6
Ammonia = 34

How many moles are there in 2.8g of nitrogen?
number of moles = mass/molar mass =
2.8/28 = 0.1

How many moles of ammonia would form?
Ammonia has 2 moles so 0.1*2 = 0.2 moles would form

Work out the mass of ammonia formed.
0.2 * 34 = 6.8g

Have I answered everything correctly? Thank you in advance.

I'm pretty sure it's correct.

Your answer is wrong - it should be 3.4g

1 mole of N2 gives 2 moles of NH3

1 mole of anything is its RAM (Mr) in g

so 1 mole of N2 is 28g and 1 mole of NH3 is 17g

so 2.8g of N2 gives 3.4 g of NH3
