Step 1Let's solve this step by step:
Step 2: Identify the given information
- Density of isopropyl alcohol = $$0.786 \frac{g}{mL}
- Volume of sample = 10.0 \, mL
Final Answer
Explanation: - We used the density formula to calculate mass - Multiplied the density (0.786 \frac{g}{mL}) by the volume (10.0 \, mL) - The result is 7.86 \, g, which corresponds to option D
