MEASUREMENTS IN SCIENCE: MASS, VOLUME, AND DENSITY

Purpose:

The purpose of this experiment is find the density of two metals using their mass and volume. Introduction:

The purpose of the experiment that was conducted was to measure and calculate the density of two different metals. Density is an important characteristic of a material. The density of an object shows how much mass is contained in the unit volume. To calculate the density of metals the experimenters had to find out the mass and volume of each and then use the following formula: d=m/V. M or mass is the amount of matter that an object contains and it can be measured using a balance. The V or volume of an object represents the space that an object occupies.

Material:

-Two types of metals

-Balance

- 80ml of water

- 100ml graduated cylinder

Procedure:

-Obtain pieces of two different metals. Determine their mass using a balance. Record your measurements. Determine their volume in the following way: Place 75-80 ml of water in a 100ml graduated cylinder. Read the volume V(in) with precision of 0.5 ml. Place the piece of metal carefully in the water. Read the new volume V(fin). Calculate the volume of the metal V(m). (Vm = Vfin-Vin). Record your results. - Calculate the density of the two metals

-Ask for density from the literature and calculate percentage error with the following formula. Percentage error= ((Density from data – density from literature) \ Density of literature) * 100

Results:

DATA | METAL 1| METAL 2|

Mass of metal (m)| 160.5g| 47.6g|

Volume of water (Vin)| 79 ml| 79ml|

Volume of water and metal (Vfin)| 98ml| 97ml|

Volume of Metal| 19ml| 18ml|

| Metal 1| Metal 2|

Literature Data| 8.96| 2.70|

Calculations:

D=m/V

Metal 1 Density= 160.5/19= 8.45

Metal 2 Density= 47.6/18= 2.64

Percentage error= ((Density from data – density from literature) \ Density of literature) * 100

Metal 1 percentage error =...
