11 GRAMS of an electrolyte was dissolved in 44 grams of water, the resulting solution
was found to have a molarity of 0.497 mol/L. The freezing point of the solution was
determined to be -2.92°C. The freezing point depression constant for water is -1.86°C
and pure water may be assumed to freeze at 0°C. If the molecular weight of the
electrolyte is 106.8 g/mol and it takes 33 minutes to perform the experiment, what is
the molarity of the solution in mol/L? Enter a numeric answer only

The molarity of the solution is 0.234 mol/L

What is the molarity of a solution?

The molarity of a solution is the amount in moles of a solute dissolved in a given volume of solvent.

  • Molarity = number of moles/ volume of solution in liters

The molarity of the solution is determined as follows:

  • Number of moles of electrolyte = mass/molar mass

mass of electrolyte = 11 g

molar mass of electrolyte = 106.8 /mol

Number of moles of electrolyte = 11/106.8 = 0.0103 moles

  • Volume of water = mass/density

density of water = 1 g/cm³

mass of water = 44 g

Volume of water = 44/1 = 44 ml or 0.044 L

Molarity of solution = 0.0103/0.044

Molarity of solution = 0.234 mol/L

In conclusion, the molarity of the solution is determined from the moles of solute and volume of solvent.
