Specific gravity of mystery fluid

  • #1
A bottle has a mass of 33.00 g when empty and 97.55 g when filled with water.
When filled with a mystery fluid the mass is 84.02 g. What is the specific gravity of the mystery fluid?


Hopefully helpful equations:
p = m/v
(p = density, m = mass, v = volume)

SG = 1000p

Attempt:
I'm really not sure how to approach this. Is there any way to find out the volumes of these substances? Or is that factor even necessary?

-------------​
Thanks in advance for any help!

You do not need to know the volume of the bottle (though it is not difficult to determine from the given information).

What is the definition of specific gravity?
