The correct Answer is:
To find out how many grams are contained in 1 gram-atom of sodium (Na), we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the term "gram-atom":** - A "gram-atom" refers to one mole of atoms. Therefore, 1 gram-atom of sodium (Na) is equivalent to 1 mole of sodium atoms. 2. **Finding the molar mass of sodium:** - The molar mass of sodium (Na) is approximately 23 grams per mole. This means that 1 mole of sodium weighs 23 grams. 3. **Calculating the mass of 1 gram-atom of sodium:** - Since 1 gram-atom of sodium is 1 mole of sodium, the mass of 1 gram-atom of sodium is simply the molar mass of sodium. - Therefore, the mass of 1 gram-atom of sodium = 23 grams. ### Final Answer: The mass contained in 1 gram-atom of Na is **23 grams**. ---
