Question

5 litres of kerosene oil is found to wiegh 4.40 kg. Find the density of kerosene oil in CGS unit

Answer 1

Explanation:

1 litre = 1000cm³

5 litre = 5×1000= 5000 cm³

Volume = 5000 cm³

density = mass÷ volume

weight = mass × gravity

mass = 4.40 ÷10 =0.44 g

density = 0.44 ÷ 5000 =8.8 g/cm³
