Specific gravity of mystery fluid

Click For Summary

Homework Help Overview

The discussion revolves around calculating the specific gravity of a mystery fluid based on mass measurements of a bottle when filled with water and the mystery fluid. The subject area includes concepts of density and specific gravity in fluid mechanics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore how to determine the volume of the bottle and question whether knowing the volume is necessary for calculating specific gravity. There are inquiries about the definitions and relationships between mass, volume, and specific gravity.

Discussion Status

The discussion is active, with participants seeking clarification on the definition of specific gravity and how to derive the necessary volume from the given mass measurements. Some guidance has been offered regarding the relationship between mass and volume, but no consensus has been reached on the approach to take.

Contextual Notes

Participants express uncertainty about the volume of the bottle and how it relates to the specific gravity calculation. There is a suggestion that the volume can be determined from the provided mass data, but this remains a point of confusion.

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!

Do you know how to find the volume of the bottle?
 
like, that's my problem because i don't know how...
 
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?
 
When the bottle is filled with water, how many grams of water are there in the bottle?

What is the specific volume of water?

What is the volume of water in the bottle?

When the water is replaced with mystery fluid, what is the volume of mystery fluid in the bottle?

How many grams of mystery fluid are there in the bottle.

What is the specific volume of the mystery fluid?
