Ted’s teacher gave him a silver-colored metal ball and told him it was made of a pure substance. (a) Ted put some water in a graduated cylinder. He then put the ball in the same graduated cylinder with the water, as shown below. What did Ted learn about the ball?
The ball displaced some water, showing its volume.
The ball dissolved in water, showing it is soluble.
The ball changed color in water, showing a chemical reaction.
The ball floated on water, showing it is less dense than water.
What else would Ted have to do before he can calculate the density of the ball?
Measure the mass of the ball
Measure the color of the ball
Measure the temperature of the ball
Measure the speed of the ball
Ted should calculate the density of the ball by:
Dividing the mass of the ball by its volume
Multiplying the mass of the ball by its volume
Adding the mass and volume of the ball
Subtracting the volume from the mass of the ball
Knowing the density and other properties of the ball will help Ted to identify the metal from which the ball is made because:
Each pure metal has unique properties such as density that can be compared to known values.
All metals have the same density and properties.
Density and properties do not help in identifying metals.
Only the color of the metal is important for identification.

The mass of reactants is always less than the mass of products.
The mass of reactants and products are unrelated.
