Answer:
diffusion
Explanation:
Diffusion can be defined as the net movement of particles from a high concentration to a low concentration. This sounds like the most plausible word in this case.
Epsom salts are hydrate of magnesium sulfate. The formula is MgSO_{4}.7H_{2}O. It has 7 water molecules.
Here, hydrate means it is bind to water molecules. Dehydration means removal of water molecules. Thus, Epsom salt in its complete dehydration loss all its water molecules and the remaining formula of dehydrated Epsom salt will be MgSO_{4} also known as magnesium sulfate.
First determine the molality of the solution. m = (w solute)/[(mm solute)(kg solvent)] -- mm means molar mass. So,
m = (14.7 g)/[(180 g/mol)(0.150 kg) =0.544 mol/kg = 0.544 m
Change in boiling point (∆t) = m x Kbp = (0.544 m)(0.512 °C/m) = 0.28°C
The solution will boil at 100.28°C at 1 atm.
the density if water is 1.00 g/ml and Kb= 0.512 C/m
