A spherical particle having a diameter of 150 microns. The density is 1.6 g / cm 3. Calculate the mass of the particle in mg. Show calculation.

Can anyone tell me if my answer is correct. With the SI unit.

V = 4/3 *pi*75^3micrometer = 1,76715*10^6 cubic micron

m= 1,6g/cm^3 * ( 1,76715*10^6)*10^-12 cm^3 = 2,83*10^-6 g
= 2,83*10^-6g*10^3 = 0,002827mg
