What effect would there be on a molar mass determination if the solute were to dimerize?

The molecules of the solvent are combining, cutting the concentration of the solvent in half. This, therefore, doubles the molar mass of the solute. Example: 1. Suppose the freezing point of a solution of 2.00 g of an unknown molecular substance in 10.00 g of the solvent benzene is measured. If the solution freezes at a temperature of 6.33°C lower than pure benzene itself, calculate the molar mass of the unknown substance. - 6.33/5.12= 1.24m, solve for x- 1.24m= x/0.01 kg, x=0.0124 mol, 2.00 g/0.0124mol=161.29 g- your molar mass - now cut the amount of solvent, 0.01Kg(10.00g), in half 1.24m=x/0.005 kg, x=0.0062 mol, 2.00 g/0.0062mol = 322.581 g, your larger molar mass

∙ 12y agoThe molar mass would increase with the forming of a dimer because the dimer decreases pressure. If you look at the ideal gas equation you will see that pressure is in the denominator, thus leading to an increase in molar mass.

What is the molar mass of a solute if 62 g of the solute in 125g of water produce a 5.3m solution?
n°moles solute = 5.3*0.125 = 0.6625 molar mass = 62.0/0.6625 = 93.58 g/mol
What effect Dimers molar mass determination volatile liquids?
I'm trying to figure out how it affects molar mass as well. However, I do know that it decreases the pressure which is in the denominator of the equation to find the molar mass once the ideal gas equation is manipulated. So i think that with the formation of dimers the molar mass would increase?
What is the mole fraction of solute in a 3.30 m aqueous solution?
This is the ratio between the molar concentration of this solute and 3,3.
What is the approximate molar mass of a molecular solute if 300 g of the solute in 1000 g of water causes the solution to have a boiling point of 101C?

What is the molarity of a solution of 4.0 moles of solute in 2.0 L total?
The value is 2 molar.
What are the formula of molarity?
This is the ratio concentration of a solute/molar mass of the solute.
How will you determine the number of moles solute?
number of moles=solute concentration/solute molar mass
How do you find how many moles are in a solute?
Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass
What term is defined as the number of moles of solute diveded by the number of liters of solute?
This is the molar concentration of the solute.

n°moles solute = 5.3*0.125 = 0.6625 molar mass = 62.0/0.6625 = 93.58 g/mol
What is the concentration of a 4.0 L solution that has 2.0 mol of solute?
The concentration of the solute is 0,5 molar.

If you are giving a quantity of solute in grams and need to convert it to moles divide the grams by?
The molecular weight. So you'll have to calculate that for the solute first. The molar mass of the solute, which is measured in grams/mole.
What is the molarity of a solution of 4.0 moles of solute in 2.0 L total?
The value is 2 molar.
What describes the number of moles of solute over the total number of moles in a solution?
This is the molar fraction.
