    6.02 x10^23 atoms present in 1 mol

    So, how many moles 2.3x10^24 atoms is = (2.3x10^24/6.02 x10^23) = 3.82 mol

    1 mol silver = 107.87 g

    So, 3.82 mol silver = 107.87*3.82 = 412.1 g

    Hope this helps

    you mean : there are 107.87 g silver / mole. (= mole mass of silver)

    I mole of silver is 107.87 g

    1 mole = 6.02*10^23 atoms

    --> 6.02*10^23 atoms = 107.87 g

    --> 2.3*10^24 atoms = 107.87*2.3*10^24/6.01*10^23 g = 412.13 g

    Convert ml to l by making use of multiplying. 0.40 4 ml * (a million l / one thousand ml) = 0.00044 l Convert min to sec by making use of multiplying. a million min * (60 sec / min) = 60 sec. 0.00044 l / 60 sec = 0.0000073 l / sec
