Transcript text: 43 Multiple Choice 1.5 points Which of the following is equal to 1.00 mole of substance? $6.02 \times 1023$ sodium atoms, Na $6.02 \times 1023$ iodine molecules, 12 $6.02 \times 1023$ sodium iodide formula units, NaI all of the above none of the above

Solution

Solution Steps

Step 1: Understand the Concept of a Mole

A mole is a unit in chemistry that represents $6.02 \times 10^{23}$ entities (Avogadro's number). This can refer to atoms, molecules, ions, or formula units.

Step 2: Analyze Each Option

Sodium atoms, Na: $6.02 \times 10^{23}$ sodium atoms is equal to 1 mole of sodium atoms.
Iodine molecules, I$_2$: $6.02 \times 10^{23}$ iodine molecules is equal to 1 mole of iodine molecules.
Sodium iodide formula units, NaI: $6.02 \times 10^{23}$ sodium iodide formula units is equal to 1 mole of sodium iodide formula units.

Step 3: Determine the Correct Answer

Since each option represents $6.02 \times 10^{23}$ entities, each is equal to 1 mole of the respective substance. Therefore, the correct answer is "all of the above."

Final Answer

The correct answer is D.
