What symbol is used for molar concentration?
It represents the number of moles per volume.
What does Rho A1 represent?
Refer to the definitions discussed in class.
True or False: Molar concentration is represented by the symbol Rho.
Recall the distinction made between mass and molar concentration.
Given that Rho A1 for a certain chemical is 50 mg/L and Rho A2 is 100 mg/L, calculate the partition constant K.
Remember the partition constant is a ratio of concentrations.
If a substance shows a mass fraction of 0.3 in the solid phase and a density of the solid of 2 g/cm³, calculate the mass of that substance in 1 kg of solid.
Use the mass fraction definition for your calculations.
