Question

Mass of an empty glass container is 50 g. When it is filled with a liquid of volume 30 mL,
mass of the container becomes 80 g. What is the density of the liquid? Find out density
also in S.I system

Answer 1

• Mass=80g-50g=30g
• Volume=30mL

We know

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

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

$\\ \sf\longmapsto Density=1g/mL$

• 1kg=1000g
• 1L=1000mL

$\\ \sf\longmapsto Density=1kg/m^3$
