WebNov 8, 2024 · First, convert grams of NaCl to moles of NaCl. From the periodic table: Na = 23.0 g/mol Cl = 35.5 g/mol NaCl = 23.0 g/mol + 35.5 g/mol = 58.5 g/mol Total number of moles = (1 mole / 58.5 g) * 6 g = 0.62 moles Now determine moles per liter of solution: M = 0.62 moles NaCl / 0.50 liter solution = 1.2 M solution (1.2 molar solution) WebMass of one mole of = 86.94 g Now, formula is given as: Number of Moles = Putting the values, Number of Moles = Number of Moles = 2.184 mol.
