Answer:

<h2><em>please</em><em> </em><em>mark</em><em> </em><em>me</em><em> </em><em>brainliest</em></h2>

Explanation:

<h2>Packing fraction is defined as a way of expressing the variation of isotopic mass from whole mass number (atomic mass). This fraction can have positive or can have negative sign. A positive packing fraction describes a tendency towards instability.</h2><h2>The equation for packing fraction is: Packing fraction = (N atoms) x (V atom) / V unit cell. N atoms is the number of atoms in a unit cell. V atom is the volume of the atom, and V unit cell is the volume of a unit cell. Substitute the number of atoms per unit cell into the equation.</h2>

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 }}
