Question

1litre of liquid weighs 700gm it's density is​

Answer 1

Answer:

Why is it that 1 litre of water weighs 1 kg while this doesn't apply for other liquids?

Empower people to live healthier lives by sharing what you know.

Litre is a unit of volume and Kg is the unit of mass.

Now, the weight of a particular volume of any substance is determined by a factor called Density.

The density of any substance is the mass (in kg) of the substance posessed by unit volume( 1 cubic meter) of the substance.

The Density of Water is approximately 1000Kg/m3.

one Litre= 1/1000 m3.

Hence converted in litre, density of water becomes 1 Kg/Litre.

hence mass of 1 L of water is 1 kg.

Now, this density is a chemical specific property. Hence for each chemical which may be an element/compound/solution etc there is a different density leading to different mass of 1 Litre of that chemical.

Hope this clarifies your doubt

Answer 2

Answer: density=mass /volume

here,mass=700gm , volume=1000ml

so,700/1000=0.7
