Making the simplistic assumption that the dissolved NaCl(s) does not affect the volume of the solvent water, determine the constants m and b in the equation Molarity = mdensity + b that relates the NaCl molarity to the NaCl(aq) density. Take the density of water to be 1.00 g/mL and the molar mass of NaCl to be 58.5 g/mol. I am having a very difficult time answering this question. There just doesn't seem to be enough information to determine the constants? Not sure what i can do.

    this is likely a linear equation right? y=mx+b Do you know how to find the equation of a line? so you need two points two molarities and the corresponding densities.

    yes, we find rise/run. I'm just unsure in what relation do you use molar mass of NaCl 58.5 and the density of water 1.00 g/mL?

    you need to molar mass to convert between molarity (in moles) and density (in mass)
