At 1 atm, equal masses of h2o(s), h2o(ℓ), and h2o(g) have (1) the same density (2) the same distance between molecules (3) different volumes (4) different percent compositions

(3) different volumes is the correct answer 

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
