Web8 de mar. de 2024 · How many molecules of NaCl does that contain? To figure this out, you will need the molar mass of NaCl which is 58.44 g/mol. First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: This calculation tells you that there are 2.1 x 10 22 molecules of NaCl in 2 grams of NaCl. Web(1) M = mol/ V (L) and due to mol = mass (g) / MW so >> M = m / (MW*V) Where, M = molar concentration (mol/L); m = mass in grams of solute MW = molecular weight of solute (g/mol) and V = volume...
