Which of the following is the correct sequence of steps to determine the density of a solid object?

• A. Measure the mass of the object, determine its volume, then divide mass by volume.
• B. Measure the mass of the object, add its volume, then divide by the mass.
• C. Measure the volume of the object, multiply by its mass, then divide by 2.
• D. Measure the volume of the object, subtract its mass, then multiply by 100.

Answer: (A)

Verified step by step guidance

1. Understand that density (\(\rho\)) is defined as the mass (\(m\)) of an object divided by its volume (\(V\)), expressed as \(\rho = \frac{m}{V}\).
2. First, measure the mass of the solid object using a balance or scale to obtain an accurate value in grams or kilograms.
3. Next, determine the volume of the solid. For regularly shaped objects, use geometric formulas; for irregular objects, use water displacement method to find the volume in cubic centimeters or liters.
4. Once you have both mass and volume, apply the density formula by dividing the mass by the volume: \(\rho = \frac{m}{V}\).
5. Interpret the result as the density of the solid, which tells you how much mass is contained in a given volume.
