i am working on my science homework. and i need to find the density of some liquids. the first question is: find the density of-liquid with the volume of 48 L and 36 kg..
what would i do??
please help me, i left my book at school. and no other website has helped.

Density is given the greek symbol rho which looks a bit like an italic "p"
Is is calculated as such: p = m / V
p = density (units are kg/m3)
m =mass (kg)
V = volume (m3)
therefore what has been written before here is true but you need to convert from litres to cubic meters (m3)
1 litre is 0.001 m3
so you need to:
48 x 0.001 = 0.048 m3
you can then do your sum:
0.048 x 36 = 1.728 kg/m3
NOTE the three in kg/m3 should be written smaller and raised (superscript in MS Word) ie an index or a "power" of 3, known as "cubed"
You should also realise that the "litre" is not a proper SI unit thats why you need to convert it to m3 which is a proper unit. Litres are merely used for convenience.

density=mass/volume
density = 36/48
density = 0.75 g per cm^3

Density Of A Liquid Formula

mass divided by volume......
The easiest way to remeber is to remeber the units of density (kg/m3) i.e. the units of mass (kg) divided by the units of density (cubic metres)

density is mass divided by volume. i believe for liquid, it should be gram divided by mL.
convert 48L to mL -> 48000mL.
36kg to g -> 36000g.
36/48 = 3/4 g/mL
or i guess g/cm^3

well, water's density is = to 1, so you could compare and contrast by pouring whatever liquid it is into water, if it sinks than it is less than 1, and if it floats its moor than 1. (an example is putting food coloring in salt water and pour it in fresh water.)

density= mass/volume
volume= mass/density
mass= density x volume
/= divided by in case u didnt know

mass/volume.
simply divide 36 by 48.

density is Mass/Volume
so for your example
density = 36kg/48L=.75kg/L or .75kg/cm^3
