Specific gravity of mystery fluid

AI Thread Summary
To determine the specific gravity of the mystery fluid, the mass of the fluid and the volume of the bottle must be established. The bottle's mass when filled with water is 97.55 g, and when filled with the mystery fluid, it is 84.02 g. The mass of water in the bottle is 64.55 g (97.55 g - 33.00 g), which corresponds to a volume of 64.55 mL, since the density of water is 1 g/mL. The mass of the mystery fluid is 51.02 g (84.02 g - 33.00 g), leading to a specific gravity calculation of approximately 0.79. Understanding these relationships allows for the determination of specific gravity without needing the bottle's volume directly.

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?

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
