how many moles of nitrogen would be needed to make 10.0 ammonia?

5.00 moles of Nitrogen2

To determine the number of moles of nitrogen needed to make 10.0 moles of ammonia, we need to know the balanced chemical equation for the reaction between nitrogen and ammonia.

The balanced chemical equation for this reaction is:

N2 + 3H2 -> 2NH3

From this equation, we can see that 1 mole of nitrogen (N2) reacts with 3 moles of hydrogen gas (H2) to produce 2 moles of ammonia (NH3).

Since we want to know the number of moles of nitrogen, we need to use the ratio of moles of nitrogen to moles of ammonia from the balanced equation.

The ratio is 1 mole of nitrogen reacts with 2 moles of ammonia.

So, to find the number of moles of nitrogen needed to make 10.0 moles of ammonia, we can set up the following proportion:

1 mole of nitrogen / 2 moles of ammonia = x moles of nitrogen / 10.0 moles of ammonia

Simplifying this proportion, we can cross-multiply:

1 * 10.0 = x * 2

10.0 = 2x

Dividing both sides by 2:

x = 5.0

Therefore, you would need 5.0 moles of nitrogen to make 10.0 moles of ammonia.
