Ответ:
The volume of ethanol is 29.14 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 of ethanol = 23 g
density = 0.7893 g/mL
volume= ?
Now we will put the values in the formula,
d= m/v
v = m/d
v = 23 g/ 0.7893 g/mL
v = 29.14 mL
The volume of ethanol is 29.14 mL.
