Question

Nitrogen gas is reacted to hydrogen gas to form nitrogen trihydride. Percent yield of 650.4 g nitrogen trihydride 150 g

Answer 1

To find the percent yield, we can use the formula:

Percent Yield = (Actual Yield / Theoretical Yield) * 100

First, we need to determine the theoretical yield of nitrogen trihydride.

From the reaction, we can see that the balanced equation is:

N₂ + 3H₂ → 2NH₃

According to the equation, 1 mole of nitrogen gas reacts with 3 moles of hydrogen gas to form 2 moles of nitrogen trihydride.

The molar mass of nitrogen trihydride (NH₃) is 17.03 g/mol.

Now we can calculate:

Theoretical Yield = (150 g Nitrogen Trihydride) * (1 mol NH₃ / 17.03 g NH₃) * (1 mol N₂ / 2 mol NH₃) * (28.02 g N₂ / 1 mol N₂) = 243.3 g N₂

Now we can calculate the percent yield:

Percent Yield = (650.4 g Nitrogen Trihydride / 243.3 g Nitrogen) * 100 = 267.1

Therefore, the percent yield is 267.1%.
