Question

A rock with a mass of 25 g is added to a graduated cylinder containing 45 mL of water. The water level rises to the 50mL mark. Based on this information, what is the density of the rock? (Hint: Density = Mass/Volume)

a 0.2 g/mL
b 0.55 g/mL
c 2 g/mL
d 5 g/mL

Answer 1

The density of the rock is calculated using the formula Density = Mass/Volume. With a mass of 25 g and a volume of 5 mL, the density comes out to 5 g/mL. Hence, the answer is d 5 g/mL.

Step-by-step explanation:

The question is about determining the density of a rock based on the water displacement method commonly used in physics. The rock has a mass of 25 g and when added to a graduated cylinder, it raises the water level from 45 mL to 50 mL. The change in water level indicates the volume of the rock, which is 5 mL (50 mL - 45 mL).

To calculate the density, you use the formula Density = Mass/Volume. Plugging in the values, you get Density = 25 g / 5 mL, which equals 5 g/mL.

Therefore, the correct answer is d 5 g/mL.
