• D. 0.99 moles

Answer: (B)

Verified step by step guidance

1. Identify the chemical formula of the compound, which is carbon tetrachloride, CCl\_4.
2. Calculate the molar mass of CCl\_4 by adding the atomic masses of one carbon atom and four chlorine atoms. Use the atomic masses: C = 12.01 g/mol, Cl = 35.45 g/mol.
3. Use the formula to find moles: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
4. Substitute the given mass (199 g) and the calculated molar mass of CCl\_4 into the formula.
5. Perform the division to find the number of moles present in 199 grams of CCl\_4.
