Step 2:: Identify the chemical formula
The chemical formula is NaHCO₃, which means we need to find the sum of the atomic masses of: - Sodium (Na) - Hydrogen (H) - Carbon (C) - Oxygen (O)
Step 3:: Look up the atomic masses
- Oxygen (O): $$m_{O} = 16.00 \mathrm{g/mol}
- Hydrogen (H): m_{H} = 1.01 \mathrm{g/mol}
Step 4:: Calculate the molar mass by summing the individual atomic masses
m_{NaHCO_{3}} = m_{Na} + m_{H} + m_{C} + 3 \times m_{O}
Step 5:: Plug in the values
m_{NaHCO_{3}} = 22.99 + 1.01 + 12.01 + 3 \times 16.00
Step 6:: Perform the calculation
m_{NaHCO_{3}} = 22.99 + 1.01 + 12.01 + 48.00 = 84.01 \mathrm{g/mol}
Final Answer
The molar mass of sodium bicarbonate (NaHCO₃) is 84.01 \mathrm{g/mol}.
