explain the procedure of finding the density of an unknown liquid using a relative density bottle
Answers
Answer:
Materials: 100ml graduated cylinder, triple beam balance, calculator, 2 unknown liquids.
Procedure: 1) Find the mass of the empty graduated cylinder.
2) Pour unknown liquid #1 into the graduated cylinder to the 50 ml. level.
3) Find the mass of the graduated cylinder with 50ml of unknown liquid #1.
4) Repeat steps 1-3 for unknown liquid #2.
We can calculate density of a each liquid using the formula:
Density= Mass/Volume
where mass is that for just the liquid (you must subtract out the mass of the graduated cylinder).
Now,
For an example,
let's calculate the densities of the two liquids using the following given data.
Liquid #1:
Given: Mass of empty graduated cylinder = 78 grams
Mass of graduated cylinder with unknown liquid #1= 128 grams.
Find:
a) Mass of just the liquid = ____
b) Volume of liquid=_____
c) Density of liquid #1 =____
Liquid #2:
Given: Mass of empty graduated cylinder = 78 grams
Mass of graduated cylinder with unknown liquid #2= 117.5 grams.
