Final answer:
The density of the rock is 1.133 grams/cm³.
Step-by-step explanation:
The density of an object can be calculated by dividing its mass by its volume. In this case, the mass of the rock is 17 grams and the volume of water displaced is 25 mL - 10 mL = 15 mL. We can convert the volume to cubic centimeters (cm³) by multiplying it by 1 cm³/1 mL, which gives us a volume of 15 cm³. The mass of the rock is 17 grams, and the change in water level from 10 mL to 25 mL indicates that the volume of the rock is 25 mL minus 10 mL, which is 15 mL or 15 cm³ (since 1 mL is equivalent to 1 cm³). The density of a substance is calculated by dividing its mass by its volume. So, the density of the rock is 17 grams / 15 cm³ = 1.133 grams/cm³.
