Avogadro's number represents the number of units in a mole. What is this value?

A. [tex]\( 3.01 \times 10^{23} \)[/tex]
B. [tex]\( 6.02 \times 10^{23} \)[/tex]
C. [tex]\( 1.20 \times 10^{24} \)[/tex]
D. [tex]\( 3.60 \times 10^{24} \)[/tex]



Answer :

Avogadro's number is a fundamental constant in chemistry that represents the number of units (such as atoms, molecules, or ions) in one mole of a substance. The value of Avogadro's number is crucial for converting between atomic and macroscopic scales.

The correct value of Avogadro's number is:

[tex]\[ 6.02 \times 10^{23} \][/tex]

Let's compare this value with the given answer choices:
1. [tex]\( 3.01 \times 10^{23} \)[/tex]
2. [tex]\( 6.02 \times 10^{23} \)[/tex]
3. [tex]\( 1.20 \times 10^{24} \)[/tex]
4. [tex]\( 3.60 \times 10^{24} \)[/tex]

From the comparison, the correct choice is clearly:

[tex]\[ 6.02 \times 10^{23} \][/tex]

Thus, the correct answer is the second option: [tex]\( 6.02 \times 10^{23} \)[/tex].
