Calculating Density of Regular and Irregular Objects

An irregularly shaped piece of gold was lowered into a graduated cylinder holding a volume of water equal to 17 ml. The height of the water rose to 20 ml. If the mass of the gold was 27 g, what was its density?

• 9 g/mL

• 10.5 g/mL

• 6.5 g/mL

• 8 g/mL

• 2 g/cm³

• 4 g/cm³

• 5 g/cm³

• 6 g/cm³

Which of the following statements is true about the relationship between mass and volume?

• Mass is always greater than volume.

• Volume is always greater than mass.

• Mass and volume are directly proportional when density is constant.

• Mass and volume are inversely proportional when density is constant.

What is the formula for calculating density?

Which method can be used to find the density of an irregular object?

• Use a ruler to measure its dimensions and calculate volume.

• Submerge it in water to find its volume and then calculate density.

• Weigh it and assume a standard volume.

• Use a scale to measure its density directly.
