Lillian Baird · Answer 1

1 Kg = 1,000g

Therefore 1.33 * 10^-7 g = 1.33 * 10^-10 kg

1m³ = 1,000,000cm³

Therefore 1 cm³ = 1 * 10^-6 m³

Dividing the mass per unit volume you get:

(1.33 * 10^-10 kg) : (1 * 10^-6 m³)

= 1.33 * 10^ (-10--6) = 1.33 * 10^ (-10 + 6) = 1.33 * 10^-4 kg/m³

Density = 1.33 * 10^-4 kg/m³
