Question: What is the number of moles in 10 grams of NaOH?

Options:

  1. 0.25
  2. 0.5
  3. 0.75
  4. 1

Correct Answer: 0.5

Solution: 

Molar mass of NaOH = 23 + 16 + 1 = 40 g/mol. Number of moles = mass/molar mass = 10 g / 40 g/mol = 0.25 moles.

Questions & Step-by-Step Solutions

What is the number of moles in 10 grams of NaOH?
  • Step 1: Find the molar mass of NaOH. This is done by adding the atomic masses of sodium (Na), oxygen (O), and hydrogen (H).
  • Step 2: The atomic mass of sodium (Na) is approximately 23 g/mol.
  • Step 3: The atomic mass of oxygen (O) is approximately 16 g/mol.
  • Step 4: The atomic mass of hydrogen (H) is approximately 1 g/mol.
  • Step 5: Add these values together: 23 g/mol (Na) + 16 g/mol (O) + 1 g/mol (H) = 40 g/mol.
  • Step 6: Now, use the formula to find the number of moles: Number of moles = mass / molar mass.
  • Step 7: Substitute the values: mass = 10 grams and molar mass = 40 g/mol.
  • Step 8: Calculate: Number of moles = 10 g / 40 g/mol = 0.25 moles.
