density

The definition of mass is

• the amount of matter in a given volume

• the amount of matter in an object

• the amount of water in an object

To find the volume of an irregular object like a rock, you would use a graduated cylinder and get the

• the formula l x w x h

• water displacement (the difference in the graduated cylinder with just water and the graduated cylinder with the rock in it)

• a ruler

Given the steps below (which are out of order), the correct order for answering a scientific question is:State Question Draw Conclusion Hypothesis Controlled Experiment Research

• 1, 5, 3, 4, 2

• 3, 5, 1, 2, 4

• 5, 4, 3, 2, 1

• 1, 5, 4, 2, 3

M = 66 g; V = 22 ml

• D = 44 g/mL;

• D = 3 g/mL;

• D = 88 g/mL;

• D = 4 g/mL;

A student found the rock shown below and used a digital scale it to determine it's mass.

After getting the mass of the rock above, what steps should the student take to find its density?

• determine its volume by how much water it displaces, then divide mass by volume

• determine its volume by multiplying length x width x height, then divide mass by volume

• crush the rock to a powder, measure its volume in a graduated cylinder, then divide mass by volume

If a wooden block were cut into eight identical pieces, the density of each piece compared to the density of the original block would be

• less

• greater

• the same

If an object's mass is 9 g and it displaces 3 mL of water, what is its density?

• 6 g/ml

• 12 g/ml

• 3 g/mL
