Question

What is the mass, in grams, of 28.58 mL of acetone?

Answer 1

If you look up the density of Acetone (Propanone in IUPAC names) you will find it is 0.7925g/cm3. This is the same as 0.7925g/ml. 

You can calculate mass using the equation:- mass = density x volume 
In your example mass = 0.7925 x 28.40 = 22.51g
I think That's right. Hope this helps!!! Good luck!

Answer 2

Answer:

22.46 g

Explanation:

For this conversion you will need the density of the substance, which formula is:

Density = mass / volume

So, clearing the mass in the equation we have:

Mass = Density x volume

As the density is a characteristic property of each substance, you can search its value in the data sheet of the substance, so you just need to replace the values in the equation. If you have that the density is 0.7857g/mL the mass will be:

Mass = (0.7857g/mL)(28.58 mL) = 22.46 g
