LAB ACTIVITY 1
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

Introduction:
Density is defined by its mass per unit volume, and is most often written in mathematical terms as; d = m / v
Mass is usually given in grams, g, and volume is given in cubic centimeters, g/cm3, or, grams per milliliter, g/mL. Density is not a property that depends upon the amount of substance present. For example, one gram of lead and one ton of lead have the same density. Density also does depend on...

The Density Challenge: A Complete Inquiry Activity
Introduction
Density has been an important part of science for a very long time. Density was discovered by Archimedes, a Greek mathematician, around 250 BC while determining whether a craftsman had replaced some of the gold in the King of Syracuse’s crown with silver. Density is the compactness of a substance. The new concept of density...

1.1 Background of the Experiment
Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids, density is represented by the ratio of its mass and volume. It is given by the equation
ρ= massvolume 1.
The SI unit of density is kg/m3. However, its CGS units, g/cm3 or...

DENSITY OF LIQUIDS
PREPARED BY BURAK COBAN
PURPOSE:
In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature, pressure, mass, volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities, so we will find out the effects of concentration on...
