To find the number of grams of ammonia (NH3) that can be made from a given mass of nitrogen gas (N2), we need to use the balanced chemical equation for the reaction between N2 and hydrogen gas (H2) to form ammonia.

The balanced chemical equation is:

N2(g) + 3H2(g) → 2NH3(g)

From the balanced equation, we can see that 1 mole of N2 reacts with 3 moles of H2 to produce 2 moles of NH3.

To use this information to calculate the grams of ammonia, we need to follow these steps:

Step 1: Convert the given mass of N2 to moles.
To do this, we can use the molar mass of N2, which is approximately 28 grams/mole.

Given mass of N2 = 250 grams
Molar mass of N2 = 28 grams/mole

Number of moles of N2 = Given mass / Molar mass
Number of moles of N2 = 250 grams / 28 grams/mole ≈ 8.93 moles

Step 2: Use the mole ratio from the balanced chemical equation to find the number of moles of NH3 produced.
From the balanced equation, we know that 1 mole of N2 reacts to produce 2 moles of NH3.

Number of moles of NH3 = Number of moles of N2 × (2 moles of NH3 / 1 mole of N2)
Number of moles of NH3 = 8.93 moles × (2 moles of NH3 / 1 mole of N2) ≈ 17.86 moles

Step 3: Convert the number of moles of NH3 to grams.
To do this, we can use the molar mass of NH3, which is approximately 17 grams/mole.

Mass of NH3 = Number of moles × Molar mass
Mass of NH3 = 17.86 moles × 17 grams/mole ≈ 303.62 grams

Therefore, approximately 303.62 grams of ammonia (NH3) can be made from 250 grams of nitrogen gas (N2).
