Answer: (B)

Verified step by step guidance

1. Identify the given quantity and what is asked: You have 1.5 moles of CO_2 and need to find the mass in grams.
2. Recall the molar mass of CO_2: Calculate it by adding the atomic masses of carbon (C) and oxygen (O). The formula is \(\text{Molar mass of CO}_2 = 12.0\,\text{g/mol} + 2 \times 16.0\,\text{g/mol}\).
3. Calculate the molar mass of CO_2 using the formula above to find the mass of one mole of CO_2 in grams.
4. Use the relationship between moles and mass: \(\text{Mass} = \text{moles} \times \text{molar mass}\). Substitute the given moles (1.5) and the molar mass you calculated.
5. Multiply the number of moles by the molar mass to find the total mass of 1.5 moles of CO_2 in grams.
