What is the mass, in grams, of a single iridium atom (#m_Ir = "192.22 u"#)?
I won't go into the calculation here, but keep in mind that this is how the conversion factor from unified atomic mass units to grams per mole looks.
Lastly, to convert between the mass of a single iridium atom and the mass of a mole of iridium atoms, use Avogadro's number.
Five sig figs are used to round the result.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
