Aluminum has a density of 2.70 g/mL. Calculate the mass (in grams) of a piece of aluminum having a volume of 238 mL .

mass in gram = 642.6 g

Explanation:

Given data:

Density of aluminum = 2.70 g/mL

Volume of aluminum = 238 mL

Mass in gram = ?

Solution:

Density:

Density is equal to the mass of substance divided by its volume.  The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

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

Now we will put the values in formula.

2.70 g/mL = m/ 238 mL

m = 2.70 g/mL × 238 mL

m = 642.6 g
