Question

question 8

what is the correct value for avogadros number?

\\(6.022 \times 10^{2.3}\\)
\\(6.022 \times 10^{23}\\)
\\(6.023 \times 10^{22}\\)
none of these
\\(6.022 \times 10^{33}\\)

Explanation:

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

Step 1: Identify Avogadro's Number

Avogadro's constant represents the number of constituent particles (usually atoms or molecules) contained in one mole of a substance.

$$ N_A \approx 6.022 \times 10^{23} \text{ particles/mol} $$

Step 2: Match with Options

• \(6.022 \times 10^{2.3}\) (Incorrect exponent)
• \(6.022 \times 10^{23}\) (Correct)
• \(6.023 \times 10^{22}\) (Incorrect exponent and value)
• \(6.022 \times 10^{33}\) (Incorrect exponent)

Answer:

\(6.022 \times 10^{23}\)
