One mole of solid MgO occupies 22.37 mm on a side. Calculate the density of MgO ( in g/cm^3) ---Steps please

Expert Solution

gram molar mass of MgO = 24+16 = 40g/mole

1 mole of solid MgO = 40g

length = 22.37mm [ 1mm = 0.1cm]

= 22.37*0.1cm = 2.237cm

volume = length * length * length

= 2.237cm*2.237cm*2.237cm = 11.194cm^3

The density = mass/volume

= 40g/11.194cm^3

= 3.57g/cm^3 >>>>answer
