🔄 Click to see definition
Definition1/16
0.630 g NaCl x (1 mol NaCl/58.44 g NaCl) = 0.0108 mol NaCl
525 g H2O x (1 kg/1000g) = 0.525 kg H2O

🔄 Click to see definition
Definition1/16
If intermolecular forces are stronger, the molecules in the
substance are more attracted to each other, and therefore requires
more energy to move. Since temperature represents average kinetic
energy, and therefore the energy present for the substance to
overcome intermolecular forces, substances with stronger
intermolecular forces will require a higher temperature to, for
instance, melt.
