Question

29. 10 liters of kerosene oil are found to weigh 6.80 kg. Find the density of kerosene oil in :
(a) CGS system
(b) SI system
​

Answer 1

Explanation:

mass = 6.8kg

volume = 10 l = 10000 cm3 = 10/1000 = 0.01m³

a. d = m/v = 6800/10000 = 0.68 m cm-³

b.

$d = \frac{m}{v} \\ = \frac{6.8}{0.01} \\ = 680 \: kg \: m { }^{ - 3}$
