Question

among these two liquids which one has lower density.justify your answer?​

Answer 1

Explanation:

The least dense substance is the gas hydrogen. Its atomic mass is 2 grams per mole. At Standard Temperature and Pressure one mole has a volume of 22.4 liters. Since density is mass over volume the density of the hydrogen gas is 2 grams divided by 22.4 liters.

Particles are less closely packed in a liquid state of matter compared to solids, taking the shape of the container in which they are stored. Liquids are difficult to compact because particles have less space to travel between them.
