Question

100 ml of Kerosene weight 82 g. Calculate the density of Kerosene in

Kg/m3​

Answer 1

Density is Mass/Volume

Mass = 82g = 0.082kg
Volume = 100ml = 1/10000 m3

Density = 0.082/ 1/10000
= 0.082 x 10000
= 820

So the density of kerosene here is 820 kg/m3

Answer 2

Volume of Kerosene used = 100mL = 10^-4

Mass of Kerosene used = 82g = 82×10^-3 Kg

Density = Mass/Volume

= 82 × 10^-3/10^-4

= 820 kg/m^3
