I need to find the density of an unknown solid. I have the mass and the volume but IDK if it is right....
Hi, thank you for the opportunity to help you with your question!
Density of a solid is given by the equation:
density = mass/volume.
This equation should give you the answer you require.
I know this, but I am not sure if my #'s are right...I did this in lab.
mass of flask with unknown metal = 40.3680g
mass of flask with unkown metal and water = 68.7555 g
the volume of flask 29.933 mL
the density was given to us, says density of water 0.99785 g/cm^3
idk if i am claculating correctly though...
i am not sure of the volume calculation...
(1) Calculate mass of water = 68.7555 - 40.368 = 28.3875g
(2) Calculate volume of water = mass/density = 28.3875/0.99785 = 28.449ml
(3) Calculate volume of metal = 29.933 - 28.449 = 1.484ml
(4) Calculate density of metal = mass/volume = 40.368/1.484 = 27.202 g/cm^3
what would be the mass of solid
That is provided in the question (40.368gm?)
