Answer:
The density of liquid is 0.87 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:
Volume of liquid = 45.4 mL
Mass of graduated cylinder = 105.56 g
Mass of graduated cylinder + liquid = 144.95 g
Mass of liquid = 144.95 g - 105.56 g =39.39 g
Density = ?
Formula:
d = m/ v
d = 39.39 g / 45.4 mL
d = 0.87 g / mL
The density of liquid is 0.87 g / mL.
