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!
