What is the density of a sample that has a volume of 2 mL and a mass of 10 grams?

• A. 5 g/mL
• B. 20 g/mL
• C. 0.2 g/mL
• D. 0.5 g/mL

Answer: (A)

Verified step by step guidance

1. Recall the formula for density, which is defined as mass divided by volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
2. Identify the given values from the problem: mass = 10 grams and volume = 2 mL.
3. Substitute the given values into the density formula: \(\text{Density} = \frac{10\ \text{g}}{2\ \text{mL}}\).
4. Perform the division to find the density value (do not calculate the final number here, just set up the expression).
5. Express the units clearly as grams per milliliter (g/mL) to complete the density calculation.
