Answer

1.81 \times 10^{24} Explanation 1. Use Avogadro's number to find molecules The number of molecules in a mole is given by **6.022 \times 10^{23} molecules/mol**. Multiply this by the number of moles: 3.00 \, \text{moles} \times 6.022 \times 10^{23} \, \text{molecules/mol} = 1.81 \times 10^{24} \, \text{molecules}.

Explanation

1. Use Avogadro's number to find molecules<br /> The number of molecules in a mole is given by **$6.022 \times 10^{23}$ molecules/mol**. Multiply this by the number of moles:<br />$3.00 \, \text{moles} \times 6.022 \times 10^{23} \, \text{molecules/mol} = 1.81 \times 10^{24} \, \text{molecules}$.
