Question

how many molecules are in 1 mol of molecules? express your answer in molecules to four significant figures.

Explanation:

Step1: Recall Avogadro's number

Avogadro's number is the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. It is approximately \( 6.022 \times 10^{23} \) per mole.

Step2: Apply Avogadro's number to 1 mole of molecules

Since we have 1 mole of molecules, the number of molecules is equal to Avogadro's number. To four significant figures, Avogadro's number is \( 6.022 \times 10^{23} \).

Answer:

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