In 3 moles of CH there are ... __ moles of Cand __ moles of H. 1 mole of Cand 4 moles of H. 3 moles of C and 3 moles of H. 3 moles of Cand 12 moles of H. 6 moles of C and 6 moles of H.

## Step 1<br />The problem involves understanding the concept of moles in chemistry. A mole is a unit of measurement used in chemistry to express amounts of a chemical substance. It is defined as exactly \(6.02214076 \times 10^{23}\) entities. These entities can be atoms, molecules, ions, or electrons.<br /><br />## Step 2<br />The given compound is CH, which means there is one atom of Carbon (C) and one atom of Hydrogen (H) in each molecule of CH.<br /><br />## Step 3<br />When we have 3 moles of CH, it means we have 3 molecules of CH. Since each molecule of CH contains one atom of Carbon and one atom of Hydrogen, we have 3 moles of Carbon and 3 moles of Hydrogen.
