Question

If you have 12g N2, how many moles of NH3 can be produced?You can use this to answer: N2 + 3H2 --> 2NH3

Answer 1

`0.857\text{ mole}`

Step-by-step explanation:

Here, we want to get the number of moles of ammonia that can be produced

From the question, we have it theoretically that 1 mole of nitrogen gave 2 moles of ammonia

To get the number of moles of ammonia produced actually, we need to get the number of moles of nitrogen

To have this, we divide the mass of nitrogen molecule by its molar mass

The molar mass is 28g/mol

The number of moles is thus:

`(12)/(28)\text{ mole}`

Since 1 mole of nitrogen gave 2 moles of ammonia

The number of moles of ammonia will be:

`(12)/(28)*2\text{ = 0.857 mole}`
