89g Pb(CH3COO)4 x 1 mol Pb(CH3COO)4 / 443.376 g Pb(CH3COO)4
= 0.20 moles of Pb(CH3COO)4
About 25 percent of energy in an organism is used by the animal that eats it .
![10.5 \times {10}^{23}](https://tex.z-dn.net/?f=10.5%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20)
multiply by (6.02 times 10^23 atoms)/(1mole, cancel out atoms)
I think the answer is B because erosion breaks down stuff while weathering moves soil.
