HELP! 1 Density-volume question!??URGENT!!

1. The problem statement, all variables and given/known data
1.An unknown liquid has a mass of 26.366g and volume of 25.24 x10^-3 liters at 25'C.
Identify the likely substance from the following information.

Substance tricholorobenzene (density:1.454g/mL)
acetone (density: 1.049g/mL)
chloride( denisty: .8862g/mL)

2. If the substance had been water with a density of .9982g/mL at 25'C, what would be its new volume?

2. Relevant equations

g/mL

3. The attempt at a solution
1.26.366g/(25.24ml) => acetone
2. i have no idea...g/mL density .9982g/mL

g/mL =density =mass/volume??? intensive physical property!!

Right.

$$d = \frac m V$$

You are given mass, you are given density - solve for V.

is the answer for 1 acetone???
is the answer for 2 25.19ml???

I know the formula already;;;;g/ML

1 - yes, 2 - no.

That's not the formula. That's - at best - density unit.

Slow down. Solve for V. Write it using symbols that I have used earlier.
