Question

equipment centigram balance graduated cylinder materials gray metal sample yellow metal sample one page of graph paper safety - always wear safety goggles when working in the lab. procedure as you perform the experiment, record your data in the table provided. 1. calibrate your centigram balance. be certain your two metal samples are clean and dry. 2. determine the mass of each of the two different metal samples to the nearest 0.001 gram. record the masses in your data table. 3. find the volume of one metal sample by water displacement: fill a graduated cylinder about half full with tap water. record this volume of water alone in the data table. 4. tilt the cylinder and carefully slide the metal sample down the side. make sure the sample is completely submerged (if not, start over with more water) measure and record this volume of water plus metal in the data table. 5. repeat steps 2 & 3 with the other metal sample. dry both samples and return them to your teacher. date pre - lab assignment. experiment name period 1. tell the meaning of the word “mass”; what dimensional unit goes with it. 2. tell the meaning of the word “volume”; what dimensional unit goes with it. 3. tell the meaning of the word “density”; what dimensional unit goes with it. 4. show the expression that relates mass, volume and density.

Explanation:

1. Mass is a measure of the amount of matter in an object. Its dimensional unit in the SI system is the kilogram (kg).
2. Volume is the amount of three - dimensional space occupied by an object. Its dimensional unit in the SI system is the cubic meter ($m^{3}$), but in the lab, milliliters (mL) or cubic centimeters ($cm^{3}$) are also commonly used.
3. Density is a measure of how much mass is contained in a given volume of a substance. Its dimensional unit in SI is kilograms per cubic meter ($kg/m^{3}$), but in the lab, grams per cubic centimeter ($g/cm^{3}$) is often used.
4. The expression that relates mass ($m$), volume ($V$), and density ($

ho$) is $
ho=\frac{m}{V}$.

Answer:

1. Mass is the amount of matter in an object. Unit: kilogram (kg).
2. Volume is the three - dimensional space an object occupies. Unit: cubic meter ($m^{3}$), milliliters (mL) or cubic centimeters ($cm^{3}$) are also common.
3. Density is mass per unit volume. Unit: kilograms per cubic meter ($kg/m^{3}$), grams per cubic centimeter ($g/cm^{3}$) is also common.
4. $

ho=\frac{m}{V}$
