Question: What is the molar mass of the product formed when 1 mole of nitrogen reacts with 3 moles of hydrogen?

Options:

Correct Answer: 28 g

Solution:

N2 + 3H2 → 2NH3. Molar mass of NH3 = 14 + 3 = 17 g.

What is the molar mass of the product formed when 1 mole of nitrogen reacts with 3 moles of hydrogen?

What is the molar mass of the product formed when 1 mole of nitrogen reacts with 3 moles of hydrogen?

Step 1: Identify the reactants. We have nitrogen (N2) and hydrogen (H2).
Step 2: Write the balanced chemical equation for the reaction. The equation is N2 + 3H2 → 2NH3.
Step 3: Identify the product formed from the reaction, which is ammonia (NH3).
Step 4: Calculate the molar mass of ammonia (NH3). The molar mass is calculated as follows: nitrogen (N) has a molar mass of 14 g/mol and hydrogen (H) has a molar mass of 1 g/mol.
Step 5: Since there are 1 nitrogen atom and 3 hydrogen atoms in NH3, the total molar mass is: 14 g/mol (for N) + 3 * 1 g/mol (for H) = 14 g/mol + 3 g/mol = 17 g/mol.
Step 6: Conclude that the molar mass of the product (NH3) is 17 g/mol.
