hydrogen reacts with nitrogen to produce ammonia. 3H2(g)+ N2(g) = 2NH3(g)
Determine how much ammonia would be produced if 100g of hydrogen reacts?

To determine the amount of ammonia produced when 100g of hydrogen reacts with nitrogen, you need to follow these steps:
Step 1: Convert the mass of hydrogen to moles.
To do this, you need to know the molar mass of hydrogen, which is 2.02 g/mol. Divide the mass of hydrogen (100g) by the molar mass to find the number of moles:
Number of moles of H2 = 100g / 2.02 g/mol = 49.5 mol (rounded to one decimal place)
Step 2: Determine the stoichiometry of the balanced equation.
From the balanced equation: 3H2(g) + N2(g) = 2NH3(g), the mole ratio between hydrogen and ammonia is 3:2. This means that for every 3 moles of hydrogen, you get 2 moles of ammonia.
Step 3: Calculate the moles of ammonia.
Using the mole ratio from step 2, multiply the number of moles of hydrogen (49.5 mol) by the ratio:
Number of moles of NH3 = (49.5 mol H2) × (2 mol NH3 / 3 mol H2)
= 33 mol NH3
Step 4: Convert moles of ammonia to grams.
To convert moles of ammonia to grams, you need to know the molar mass of ammonia, which is 17.03 g/mol.
Mass of NH3 = Number of moles of NH3 × molar mass of NH3
= 33 mol × 17.03 g/mol
= 561.99 g (rounded to two decimal places)
Therefore, if 100g of hydrogen reacts with nitrogen, it will produce approximately 561.99 grams of ammonia.
