Dilution Units

Postby Dustin Shin 2I » Fri Nov 02, 2018 12:26 pm

In terms of dilution, will the solute being dissolved in the solution always be in terms of moles for its units? I got marked down on the first test for leaving my answer in grams even when it asked for grams, so I just want to know to clarify things going forward. In addition, what units will the solvent be in?

For dilutions or calculating the molarity, the unit is always mol/liters. So if you were given the grams of the solute and you need to calculate the molarity, you would need to use the molar mass to change that to mols.
Generally, I don't think we would be asked what the concentration of the solvent is but possibly the volume of the whole solution, which would be in liters.
