EXPERIMENT
 CALCULATE THE DENSITY OF LIQUID IN BELLOW!
A) MATERIAL:
1] JUICE
2] SUNLIGHT
3] COCONUT OIL
4] WATER
5] MEASURING GLASS
6] PLASTICS
7] BALANCE
B) SOLUTION:
A] STEPS:
1] FIRST STEP:
Prepare the material
Each material entering into measuring glass which different until 100cm3
Then, each material entering into plastic which different
Then, calculate the mass of each material using balance
Then, calculate the density of each material


2] SECOND STEP
Prepare material which into plastic a while ago
Then, mixed the material into 1 in the measuring glass
Then, entering into plastic
Then, calculate the mass using balance
Then, calculate the density of this



C) RESULT:
1] FIRST RESULT
NO MATERIAL MASS (gram) VOLUME (cm3) DENSITY (g/cm3)
1 Water 100 g 100 cm3 1 g/cm3
2 Sunlight 100 g 100 cm3 1 g/cm3
3 Juice 100 g 100 cm3 1 g/cm3
4 Coconut oil 75 g 100 cm3 0.75 g/cm3

1] The density of water is same with sunlight
2] The density of sunlight is same with juice
3] The density of juice is greater than coconut oil
So, the density of water,sunlight,juice is greatest, and coconut oil is smallest

2] SECOND RESULT [mixture]
Material: mixture from water,sunlight,juice,coconut oil
Mass :375 g
Volume :400 g
Solution: P= mass m
volume v
357 g 0.9375 g/cm3
400 cm3
