 Trial 1
 Trial 2
 Trial 3
What do I do to find the density?

Answer 3

Part I: Density of Unknown Liquid
1. Calculate the mass of the liquid for each trial.

?? how do you calculate the mass of the liquid ...

Answer 4

yes

Answer 5

you can't just keep the liquid directly on a scale ... it would flow off...

you need to keep it in a container ... like the cylinder ...

so, to find the mass of just the liquid:
you have to find the mass of the cylinder with the liquid in it...
and subtract the mass of the empty cylinder.

Answer 6

after that: \[\large density = {mass \over volume}\]
