Question

The density of mercury is 13.6 g cm^-3 in CGS system. Find its value in SI unit.​

Answer 1

Answer:

Explanation:

SI unit of density is Kg/m³

1 m = 100 cm => 1 cm = 10-² m

1 Kg = 1000g => 1g = 10-³ Kg

now,

13.6 g/cm³ = 13.6 × ( 10-³)/(10-²)³ Kg/m³

= 13.6 × 10-³/10^-6 Kg/m³

= 13.6 × 10^(-3 + 6) Kg/m³

= 13.6 × 10³ Kg/m³
