Non-polar Solute and Polar Solvent (and vice versa)
However the molecules in the solute and solvent are only able to make dispersion forces with each other (as they aren't both polar). This only releases very little energy. Therefore overall, more energy is required than released and hence the process won't happen.
Hey there!
Molar mass NaCl = 58.44 g/mol
number of moles:
n = m / mm
n = 15.0 / 58.44
n = 0.2566 moles of NaCl
Volume in Kg :
50.0 g / 1000 => 0.05 Kg
Therefore :
Molality = moles of solute / volume
Molatity = 0.2566 / 0.05
Molality = 5.132 mol/kg
Answer:
I believe it to be a difference in isotopes.
Explanation:
This is because since both are the same element it cannot be allotropes which are on a molecular level so it must be isotopes.
