Question

a beaker filled with 30 cm cube of kerosene weighs 70 gram the beaker alone weighs 46 gram find the density of the kerosene.​

Answer 1

Answer:-

• Beaker alone weighs=46g
• Beaker weighs with kerosene =70g
• Mass of kerosene=70-46=24g
• Volume=30cm^3

We know that

$\boxed{\sf Density=\dfrac{Mass}{Volume}}$

$\\ \sf \longmapsto Density=\dfrac{24}{30}$

$\\ \sf \longmapsto Density=\dfrac{4}{5}$

$\\ \sf \longmapsto Density=0.8g/cm^3$
