Question

1.1 g ice cube raises the level of water in a 10 mL graduated cylinder 1.2 mL. What is the density of the ice cube?

A) 0.11 g/mL
B) 0.92 g/mL
C) 1.2 g/mL
D) 1.44 g/mL

Answer 1

To find the density of the ice cube, we divide its mass by its volume. The volume of the ice cube can be calculated by finding the difference in volume before and after it is added to the water. By substituting the given values into the formula, we find that the density of the ice cube is 0.92 g/mL, which corresponds to option B.

Step-by-step explanation:

To find the density of the ice cube, we need to use the formula for density: Density = Mass/Volume.

Given that the ice cube raises the level of water in a 10 mL graduated cylinder by 1.2 mL, we can calculate the volume of the ice cube as the difference in volume before and after the ice cube is added: Volume of ice cube = Volume after - Volume before = 10 mL + 1.2 mL - 10 mL = 1.2 mL.

Next, we need to calculate the mass of the ice cube. Since the density of ice is 0.92 g/mL (according to your referenced information), the mass of the ice cube can be found by multiplying the density by the volume: Mass = Density * Volume = 0.92 g/mL * 1.2 mL = 1.104 g.

Lastly, we can find the density of the ice cube by dividing the mass by the volume: Density = Mass/Volume = 1.104 g/1.2 mL = 0.92 g/mL.

Therefore, the density of the ice cube is 0.92 g/mL, which corresponds to option B.
