What is the boiling point in °C) of a 0.321 m
aqueous solution of NaCl?
Enter your rounded answer with
3 decimal places.
Kp for water = 0.512 °C/m

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.

b.final

im pretty sure its b
