Data Tables:

You should copy these tables into your lab report in the data/result section.

 

Density Determination of Regular Object (textbook, light weight)

 

  Trial 1 Trial 2 Trial 3
Mass of the light textbook in g      
Length of the light textbook in cm      
Width of the light textbook in cm      
Height of the light textbook in cm      
Volume of the light textbook in cm3      
Density of the of light textbook in g/cm3      

 

Answer the questions below and copy your answer in the data section of your lab report.

Inspect the measured volume and mass of the light weighed textbook in the 3 trials.

What is the conclusion you can deduce from your measured data? Are your measurements precise? Yes or No and Why?

 

Density Determination of 10.0 mL of water at room temperature

  Trial 1 Trial 2 Trial 3
Mass of the empty graduated cylinder in g      
Mass of the filled graduated cylinder in g      
Mass of the 10.0 mL tap water in g      
Volume of tap water in mL 10.0 10.0 10.0
Density of the 10.0 mL in g/mL      

 

Average density of the 10.0 mL in g/mL =

% Error =

 

Density Determination of 20.0 mL of water at room temperature

 

 

  Trial 1 Trial 2 Trial 3
Mass of the empty graduated cylinder in g      
Mass of the filled graduated cylinder in g      
Mass of the 20.0 mL tap water in g      
Volume of tap water in mL 20.0 20.0 20.0
Density of the 20.0 mL in g/mL      

 

Average density of the 20.0 mL in g/mL =

% Error =

 

Answer the questions below and copy your answer in the data section of your lab report.

 

Compare the density values of 10.0 mL and 20.0 mL tap water.

Are the values of the density close to each other? Yes or No?

Is the density an intensive or an extensive property of the matter based on the values of 10.0 mL and 20.0 mL tap water?

 

Density of Determination of Irregular Shape Object (pennies)

 

  Trial 1 Trial 2 Trial 3
Mass of ALL 20 pennies in g      
Initial volume reading of the tap water in graduated cylinder in mL 10.0 10.0 10.0
Final volume reading of the tap water in graduated cylinder in mL      
Volume of ALL 20 pennies in mL      
Density of the ALL 20 pennies in g/mL      

 

Average density of the ALL 20 pennies in g/mL =

% Error =

 

Determine whether your used pennies are old or new minted pennies. Include your reasoning in the data section of your lab report.
