Chem question (please help if you can :)?
"You are given a bottle that contains 4.59cm3(cubed) of a metallic solid. The total mass of the bottle and solid is 35.66g. The empty bottle weighs 14.23 g. What is the density of the solid? Mercury is traded by the "flask" , a unit that has a mass of 34.5kg. What is the volume of a flask of mercury if the density of mercury is 13.5g/mL?"
Sorry, a big question that I do not understand. If you have the answer, can you please explain how you got it. Thanks :)

Mass of bottle − empty bottle = mass of metallic solid
35.66 g − 14.23 g = 21.43 g
Density = Mass/Volume
x g/cm³ = (21.43 g) / (4.59 cm³)
= 4.70 g/cm³
So the density of the metallic solid is 4.70 g/cm³ (or g/mL).
Volume = Mass/Density
x mL = (34.5 kg) / (13.5 g/mL)
x mL = (34500 g) / (13.5 g/mL)
= 2555.55 mL = 2.56 LSource(s): Er... head. No guarantees on correctness.

This is two questions... I hate when they squish two questions together, it only confuses people.
35.66g - 14.23g = mass of solid
mass of solid / 4.59cm3 = density (D=M/V)
Again D = M / V so, if we want the volume, solve for V.
V = M / D
34.5kg / 13.5g/mL = the volume of a "Flask" of mercury
you can easily find the answers from this information... I'm just feeling extra lazy this evening, so I won't answer the question directly... Sorry... hope I helped enough.
