Converting between Moles, Mass and Number of Particles Number of Particles to Mass Chemistry 11 Ms. McGrath

Number of Particles to Mass What is the mass of 5.67 x 1024 molecules of cobalt (II) chloride, CoCl2? Convert the number of molecules into moles by dividing by the Avogadro’s constant. Convert the number of moles into grams by multiplying it by the molar mass of cobalt (II) chloride.

Number of Particles to Mass Convert number of particles into moles n = N NA n = 5.67 x 1024 molecules 6.02 x 1023 molecules / mol n = 9.42 mol

Number of Particles to Mass 2. Convert the moles to mass MCoCl2 = 58.93 g / mol + 2(35.45 g / mol) = 129.84 g / mol m = n x M = 9.42 mol x 129.84 g / mol = 1.22 x 103 g
