Question

question 10

one mole of copper atoms is \\(6.022 \times 10^{23}\\) copper atoms.

true
false

Explanation:

⚡ Using what you learned: mole-to-mass and mole-to-particle conversions

Step 1: Analyze the definition of a mole

A mole is a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or formula units.

By definition, one mole of any substance contains Avogadro's number of representative particles:

$$ 1\text{ mole} = 6.022 \times 10^{23}\text{ particles} $$

Step 2: Apply to copper atoms

Since copper is an element, its representative particles are individual atoms. Therefore, one mole of copper atoms contains exactly:

$$ 6.022 \times 10^{23}\text{ copper atoms} $$

The statement is correct.

Answer:

True
