    This is not a question from a book.

    I know that Cobalt-60 has the atomic mass of 59.933817059u. How can I get the amount of moles in 1μ Cobalt-60?

    I know that ##n=\frac{m}{M}## but I cant really ply it here it seems.
    Can anyone help me please?

    I don't see why it can't be applied here.

    Alright so I have the mass which is 1μg. But how can I turn that u thingy into M?

    Doesn't M=59.934 g/mol ?

    Then there is 1.668507... × 10^-8mols in 1 microgram Co-60. Thank you.
