What is the molality of NaCl in a solution that is 3.000 M NaCl with a density of 1.07 g/mL?
Question:
What is the molality of NaCl in a solution that is 3.000 M NaCl with a density of 1.07 g/mL?
Molality:
When we prepare a solution (homogeneous mixture) we describe the abundance of each solute inside as a concentration. There are many valid choices for the concentration parameter, with the common choice in chemistry being the molar concentration (molarity). The abbreviation of "M" corresponds to units of mol/L, representing the solute moles dissolved per liter volume of the solution. The solution volume has a certain total mass, which is related to the solution's density. This can be used as a conversion factor to determine the closely related solute concentration parameter known as the molality, which has units of mol/kg.
