A mystery compound dissolves in water to produce a solution that does not conduct electricity. The compound cannot be . Select one:
a. ethanol
b. sodium chloride
c. butane
d. benzene

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

if you're asking what comes out, it's steam.
