Final answer:
Option C: The molar mass of ammonia (NH₃) is calculated by adding the molar masses of one nitrogen atom and three hydrogen atoms, resulting in approximately 17.04 g/mol, making (c) 17 g/mol the correct answer.
Step-by-step explanation:
The molar mass of ammonia, NH₃, can be calculated by summing the molar masses of its constituent elements. Nitrogen (N) has a molar mass of approximately 14.01 g/mol, and hydrogen (H) has a molar mass of about 1.01 g/mol. Since ammonia has one nitrogen atom and three hydrogen atoms, its molar mass is:
The molar mass of ammonia, NH₃, can be calculated by adding up the atomic masses of nitrogen (N) and hydrogen (H). The atomic mass of nitrogen is 14.01 g/mol and the atomic mass of hydrogen is 1.01 g/mol. Since ammonia has one nitrogen atom and three hydrogen atoms, we can calculate the molar mass as follows:
Molar mass of NH₃ = (1 x atomic mass of N) + (3 x atomic mass of H)
Molar mass of NH₃ = (1 x 14.01 g/mol) + (3 x 1.01 g/mol)
Molar mass of NH₃ = 14.01 g/mol + 3.03 g/mol
Molar mass of NH₃ = 17.04 g/mol
Therefore, the correct answer is (c) 17 g/mol.
1 N × 14.01 g/mol + 3 H × 1.01 g/mol = 14.01 g/mol + 3.03 g/mol = 17.04 g/mol.
Therefore, the correct answer is (c) 17 g/mol, which represents the molar mass of ammonia.
