Question

Density of oil is 0.8 g cm³ in C.G.S. unit. Find its value in S.I. units.

Answer 1

Dimensions of density is [L^-3M¹T⁰]

0.8 g cm^-3 = conversion factor \((n)\times\,Kg\) m^-3 .....(1)

= 0.8 [10^-3] [10^-2]^-3

= 0.8 [10^-3] [10]⁶

n = 0.8 × 10³

Substituting the value of ‘n’ in equation (1).

we get, 0.8 g cm³ = 0.8 × 10³ kg m^-3.

Density of oil in S.l unit is 0.8 × 10³ kg m^-3.
