Aliquid that occupies a volume of 0.820l has a mass of 2.56kg. what is the density of this liquid in kg/l

Mass = 2.56 kg

volume = 0.820 L

density = mass / volume

D = 2.56 / 0.820

D = 3.121 kg/L

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts

C. definite shape, definite volume. that is a solid.
