Question
A graduated cylinder contains 50 mL of water. You carefully place a rock into the cylinder, causing the water level to rise to 70 mL. If the mass of the rock is 100 grams, explain how to calculate the density of the rock in two to four sentences. Describe each step of the process and provide the final density value for full points. You may write your answer in complete sentences or as a numbered/bulleted list but you must explain all steps for full points

1) Determine the rock's volume by displacement: final volume (70 mL) minus initial volume (50 mL) = 20 mL displaced.
2) Convert/recognize units: 1 mL = 1 cm³, so the rock's volume = 20 cm³.
3) Calculate density = mass/volume = 100 g / 20 cm³ = 5 g/cm³ (which is also 5 g/mL).
2) Convert/recognize units: 1 mL = 1 cm³, so the rock's volume = 20 cm³.
3) Calculate density = mass/volume = 100 g / 20 cm³ = 5 g/cm³ (which is also 5 g/mL).
