What is the density (g/ml) of a sample of mineral oil if 250 ml has a mass of 0.23 kg?

• A. 1.00 g/ml
• B. 1.15 g/ml
• C. 0.92 g/ml
• D. 0.46 g/ml

Answer: (C)

Verified step by step guidance

1. Identify the given quantities: volume \(V = 250\ \text{ml}\) and mass \(m = 0.23\ \text{kg}\).
2. Convert the mass from kilograms to grams because density is typically expressed in grams per milliliter. Use the conversion \$1\ \text{kg} = 1000\ \text{g}\(, so \)m = 0.23 \times 1000 = 230\ \text{g}$.
3. Recall the formula for density: \(\text{density} = \frac{\text{mass}}{\text{volume}}\).
4. Substitute the values into the density formula: \(\text{density} = \frac{230\ \text{g}}{250\ \text{ml}}\).
5. Perform the division to find the density in \(\text{g/ml}\) (do not calculate the final number here, just set up the expression).
