What mass does 35.6ml of hexane have if it’s density is approximately 0.56g/ml

Mass of hexane is  19.94 g.

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 hexane = 35.6 mL

Density = 0.56 g/mL

Mass = ?

Solution:

d = m/v

m = d × v

m =  0.56 g/mL × 35.6 mL

m =  19.94 g
