<span>Calcium crystal has a face center cubic (FCC) structure. For FCC structure,
relation between edge length (a) and radius (r) is
a = 2</span>√2 r
<span>Given: r = 180 pm
Therefore, a = 2</span>√2 180
<span> = 2 x 1.141 x 180
= 410.76 pm
</span><span>The length of the edge of the Ca unit cell is 410.76 pm.</span><span>

<span>1.4 moles of aluminium metal is exposed to 1.35 mol of oxygen
Theoretical yield=0.007 mol
calculate % yield
% yield= actual yield/theoretical yield*100
% yield= 0.938/0.700*100
% yield= 13.4% yield</span>
