<insert step 1: Identify the molar mass of each compound.>
<insert step 2: Use the formula for moles: \( \text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \).>
<insert step 3: For each compound, divide the given mass by its molar mass to find the number of moles.>
<insert step 4: For CCl4, calculate the molar mass by adding the atomic masses of 1 C and 4 Cl atoms.>
<insert step 5: Repeat the process for C12H22O11, C2H2, and dinitrogen monoxide, using their respective molar masses.>
