How many atoms of Lead are in a 62.7 g sample of Lead(II) permanganate?
Alexandra [31]

Answer:

\large \boxed {8.48 \times 10^{22}\text{ atoms}}

Explanation:

1 mol of Pb(MnO₄)₂contains 1 mol of Pb atoms.

1. Moles of Pb

\text{Moles of Pb} = \text{62.7 g Pb(MnO$_{4}$)}_{2} \times \dfrac{\text{1 mol Pb(MnO$_{4}$)}_{2}}{\text{445.07 g Pb(MnO$_{4}$)}_{2}}\\\\\times \dfrac{\text{1 mol Pb}}{\text{1 mol  Pb(MnO$_{4}$)}_{2}} = \text{0.1409 mol Pb}

2. Atoms of Pb

\text{Atoms of Pb} = \text{0.1409 mol Pb } \times \dfrac{ 6.022  \times 10^{23}\text{ atoms Pb }}{\text{1 mol Pb }}\\\\= \large \boxed {\mathbf{8.48 \times 10^{22}}\textbf{ atoms Pb }}
