Answer:
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.
Taking into account the definition of density, the density of the sample of an unknown liquid is 0.2 [tex]\frac{g}{mL}[/tex].
First it is necessary to know that density is defined as the property that matter, whether solids, liquids or gases, has to compress in a given space. That is, the density is the ratio between the weight (mass) of a substance and the volume that the same substance occupies.
Then, the expression for the calculation of the density is the quotient between the mass of a body and the volume it occupies. :
[tex]density=\frac{mass}{volume}[/tex]
In this case, you know that:
Replacing in the definition of density:
[tex]density=\frac{6 g}{30 mL}[/tex]
Solving:
density=0.2 [tex]\frac{g}{mL}[/tex]
In summary, the density of the sample of an unknown liquid is 0.2 [tex]\frac{g}{mL}[/tex].
