• A. 2,520.1 g
• B. 2,520.22 g
• C. 2,520 g
• D. 2,520.81 g

Answer: (D)

Verified step by step guidance

1. Identify the given information: the molar mass of octane (C\_8H\_{18}) is 114.22 g/mol, and the amount of substance is 22.05 mol.
2. Recall the formula to calculate mass from moles and molar mass: \(\text{mass} = \text{moles} \times \text{molar mass}\).
3. Substitute the given values into the formula: \(\text{mass} = 22.05\ \text{mol} \times 114.22\ \text{g/mol}\).
4. Perform the multiplication to find the mass in grams (do not round prematurely to maintain accuracy).
5. Express the final answer with appropriate significant figures based on the given data.
