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!

To find the molar concentration (mol/L) of the NaCl solution, follow these steps:
Step 1: Find the molar mass of NaCl
The molar mass of NaCl is calculated by adding up the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of sodium is 22.99 g/mol, and the atomic mass of chlorine is 35.45 g/mol. Adding them together, we get:
Molar mass NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
Step 2: Use the mass concentration to find the number of moles of NaCl
Given that the mass concentration of the NaCl solution is 58.5 g/L, you have 58.5 grams of NaCl per liter of solution.
To convert this mass into moles, divide the mass by the molar mass of NaCl:
Moles NaCl = 58.5 g NaCl / 58.44 g/mol = 1 mol NaCl
Step 3: Convert moles to molar concentration
The molar concentration is given by the number of moles of substance divided by the volume of the solution in liters. In this case, the volume is 1 liter.
Therefore, the molar concentration (mol/L) of the NaCl solution is:
Molar concentration = 1 mol NaCl / 1 L solution = 1 mol/L
So, the molar concentration of the NaCl solution is 1 mol/L.
