Calculate the weight of :
10.0 g atoms of sodium.

Explanation

To calculate the weight of 10.0 gram atoms of sodium, we can follow these steps:

### Step 1: Understand the concept of gram atoms
A gram atom (or mole) is the amount of a substance that contains the same number of entities (atoms, molecules, etc.) as there are in 12 grams of carbon-12. For sodium, the atomic weight is approximately 23 grams per mole.

### Step 2: Identify the molecular weight of sodium
The molecular weight (or atomic weight) of sodium (Na) is 23 grams per mole. This means that 1 gram atom of sodium weighs 23 grams.
