You have a 23-g sample of ethanol with a density of 0.7893 g/ml. what volume of ethanol do you have?
zhannawk [14.2K]

Answer:

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.
