Question

PART E: Final Challenge Cut a piece of aluminum foil to the right size so that it will contain \( 4.5 \times 10^{22} \) atoms. Show this to your instructor to be sure you took the right amount. To help, you will need to know that aluminum has an average mass of \( 26.98 \mathrm{~g} / \mathrm{mol} \), and that Avogadro' number of atoms is \( 6.02 \times 10^{23} \) atoms/mole. Calculations: \[ 26.98 \mathrm{~g} / \mathrm{mol} \] Put \( 8.3 \times 10^{23} \) molecules of sand in a beaker. Show this to your instructor to b you took the right amount. Sand has a molecular formula of \( \mathrm{SiO}_{2} \), the averag Si is \( 28.09 \mathrm{~g} / \mathrm{mol} \), the average mass of \( O \) is \( 16.00 \mathrm{~g} / \mathrm{mol} \), and Avogadro's nur molecules is \( 6.02 \times 10^{23} \) molecules/mole.
