To calculate the number of moles of iron in a 50-pound mass of iron, you need to first convert the mass from pounds to grams, and then use the molar mass of iron to find the number of moles.
1 pound is approximately equal to 453.592 grams.
The molar mass of iron (Fe) is approximately 55.845 grams per mole.
First, convert the mass from pounds to grams: [ 50 , \text{pounds} \times 453.592 , \text{grams/pound} = 22679.6 , \text{grams} ]
Then, calculate the number of moles of iron: [ \text{Number of moles} = \frac{\text{Mass in grams}}{\text{Molar mass}} ] [ \text{Number of moles} = \frac{22679.6 , \text{grams}}{55.845 , \text{grams/mol}} ]
[ \text{Number of moles} \approx 406.07 , \text{moles} ]
Therefore, there are approximately 406.07 moles of iron in a 50-pound mass of iron.

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.
