Acetone, a common solvent, has density of 0.79g/cm3 at 20 degrees Celsius. what is the volume of 85.1 g of acetone at 20 degrees Celsius? what is the mass of 125 ml of acetone at 25 degrees Celsius?

Do you know what formulas are involved here?

anonymous · Answer

I have no clue

dtan5457 · Answer

I am confident that the first one just requires the knowledge that

density=mass/volume

dtan5457 · Answer

0.79 g/cm=85.1/v

dtan5457 · Answer

to solve for v, divide mass by density.

dtan5457 · Answer

That should be be roughly 107.7cm for volume

dtan5457 · Answer

for the 2nd, one because they already gave you new volume with a new temperature. I don't believe you need to use charles law.

instead, same thing as before, use the density formula to calculate mass

dtan5457 · Answer

m=volume x density

alright, thanks alot, really do appreciate it!

I hope someone checks this for you, chemistry is hard in the sense of all the pressure, temp, relationships etc. hard to know what laws to use...
