If you know that the mass concentration of a NaCl solution is 58.5 g/L, the molar concentration (mol/L) of the solution is ?
can sum1 help me plz
1 mol of NaCl has a mass of what?
58.5 g NaCl x (1 mol NaCl/molar mass NaCl) = mols NaCl on 58.5 gg NaCl.
Mols NaCl/Liter of solution = molarity.
i still don't kno how to do this so when u get a solution let me kno!
1.2molar solution affedto 0.6nacl to make0-75molar
