Asample of an unknown liquid has a volume of 30.0 ml and a mass of 6 g. what is its density? show your work or explain how you determined this value.

0.2 g/mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

d=m/v

d= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

mass = 6 g

volume = 30.0 mL  

density = ?  

Now we will put the values in the formula,

d= m/v

d= 6 g/ 30 mL

d= 0.2 g /mL

so, the density of unknown liquid is 0.2 g/mL.
