### Step-by-Step Solution: 1. **Understanding C4 Photosynthesis**: - C4 plants have a unique photosynthetic pathway that allows them to efficiently fix carbon dioxide. This pathway involves two types of cells: mesophyll cells and bundle sheath cells. 2. **Role of Mesophyll Cells**: - In C4 plants, carbon dioxide is initially fixed in the mesophyll cells into a four-carbon compound, typically malate or aspartate. This process occurs in the presence of the enzyme PEP carboxylase, which has a high affinity for carbon dioxide. ...

A chemical commonly called "dioxin" has been very much in the news in the past few years. (It is the by product of herbicide manufacture and is thought to be quite toxic.) Its formula is C_(12)H_(4)Cl_(4)O_(2) . If you have a sample of dirt (28.3 g) that contains 1.0xx10^(-4)% dioxin, how many moles of dioxin are in the dirt sample?
