How much heat is emitted when 65.4 g of isopropyl alcohol condenses at 25 ∘C? The heat of vaporization of isopropyl alcohol at 25 ∘C is 45.4 kJ/mol.

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.

i'm pretty sure it is letter c.) car
