Introduction:The porpuse of this experiment is to determine the density of water, oil and alcohol.
Materials:
Scales
Oil
3 glasses
Alcohol
Water
Test tube
Steps:
- At first to weight the liquids
- Then to weight
- Next to measure 100ml of water in the glass and to determine the mass to subtract the value of glass (the repeat the step with the oil and alcohol.
- Finally to calculate the density of water, oil and alcohol
Substances Mass Volume Density
Water 18.3 g 20ml 0.91 g/ml
Oil 12.2 g 20ml 0.61 g/ml
Alcohol 19.9 g 20ml 0.64 g/ml
Discussion:
We found that our hypothesis was correct as we predicted because the water is more dense.
