The maximum amount of salt that can be dissolved in water at 100C is 391g/L. Calculate the molar concentration in this case, knowing that 1 mole of water has 18g and 1 mole of salt has 58.5g.
Homework Answers
Given 391 gram salt can dissolve in 1L of water.
So, moles of salt that can dissolve = mass/molar mass
= 391/58.5 = 6.6837 gram
Now, molar concentration = moles of salt/volume of solution
= 6.6837/1.00 = 6.6837 M

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...

A solution of water and dissolved salt enters a cylindrical
vessel with radius R. The volumetric inlet flow rate of solution in
the vessel is q1 and the concentration of salt in the inlet is c1.
The solution inside the vessel is kept well-stirred (assume perfect
