mass of element = 311.1269 amu
what is mass of 1.36 moles of these atoms in g
Hint: (1 mol = 6.022 x 1023 atoms) and (1 amu = 1.6606 x 10-24 g)


  • chem -

    mass=number of moles* mass element/mole

    You are given the mass element in amu, multilply that by grams/amu (1.66E-24g/amu * 6.022E23amu/mole)

  • chem -

    can someone help me work it out please?
