Final answer:
The conversion factor used to convert from volume to molar mass is expressed in g/L. This conversion factor helps convert from a volume concentration to a molar concentration by using the molar mass of the substance. The process involves converting grams to moles and then dividing by the volume of the solution in liters.
Step-by-step explanation:
The conversion factor that is used when converting from volume to molar mass is expressed in the units g/L. This conversion factor allows you to convert from a volume concentration to a molar concentration. Let me explain how to use this conversion factor step by step:
- Start with the given volume concentration, which is expressed in g/L.
- Use the molar mass of the substance to convert grams to moles. The molar mass is the mass of one mole of the substance and is expressed in g/mol.
- Finally, divide the number of moles by the volume of the solution in liters to obtain the molar concentration in mol/L.
For example, if you have a volume concentration of 1.25 g/L and the molar mass of the substance is 28.02 g/mol, the molar concentration would be:
Molar concentration = (1.25 g/L / 28.02 g/mol) = 0.0446 mol/L
