Dilution with Salt & Sugar Solutions and Water Questions

Making a dilution with salt & sugar solutions and waterRequest from the prep area the following equipment:
Measuring cup
Stir Stick or Blender
Make sure you bring:
YOUR SOLUTION SUGAR SOLUTION
YOUR SOLUTION SALT SOLUTION
Make the following dilutions:
1)
Take 25 mL of 1M solution of sugar and dilute to 50 mL
2)
Take 25 mL of 1M solution of salt and dilute to 50 mL
Molarity is a measure of concentration, and has units of:
Moles of solute
moles
M = —————————– = ——————-Liters of solution
liters
Show calculations first to instructor before making the dilution of salt and sugar solutions. The dilution
equation for solutions is:
M 1 x V1 = M 2 x V2
or
M I x VI = M F x VF
In your report calculate the new mass % of sugar & mass % of salt.
Moles of solute
Also calculate the new molality (m) for each solution (m = ———————-).
Kg of solvent
CALCULATE the NEW MOLE FRACTIONS OF THE SOLUTE FOR EACH SOLUTION .
Dispose of the solutions in the waste container.
Making a solution with salt, sugar and water
You will need the following equipment:
MEASURING CUP (convert ounces to milliliters to liters)
BLENDER OR SPOON
Make sure you have:
Sugar
Salt
Make the following solutions:
50 mL of 1M solution of sugar
50 mL of 1M solution of salt
Molarity is a measure of concentration, and has units of:
Moles of solute
moles
M = —————————– = ——————-Liters of solution

Show all calculations FOR making the salt and sugar solutions in report’s data section. The molecular
formula for salt is NaCl; and the molecular formula for sugar is C 12H22O11. Also give a step-by-step
depiction of how you conducted the experiment noting colors, smells and reactions. Record in the
video the making of both solutions.
In your report calculate mass % of sugar & mass % of salt.
Moles of solute
Also calculate molality (m) for each solution (m = ———————-).
Kg of solvent
CALCULATE MOLE FRACTIONS OF THE SOLUTE FOR EACH SOLUTION .
