WebNov 8, 2024 · 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) Note that I assumed dissolving the 6 grams of salt did not appreciably affect the volume of the solution. WebMass of one mole of any element = gram atomic weight ( found in the periodic table) example: mass of 1 mole Carbon = 12 g Mass of one mole of any ionic compound = gram formula weight example: mass of 1 mole of NaCl = add the atomic weight of each element ( 23 + 35.45)= 58.45 g Mass of one mole of any covalent compound = gram molecular weight
