Final answer:
To calculate the number of moles of iron in a 1 gram paper clip, divide 1 gram by the molar mass of iron, which is 55.85 g/mol, yielding approximately 0.0179 moles of iron.
Step-by-step explanation:
To determine the number of moles of iron in a 1-gram paper clip, we first need to find out the molar mass of iron. The molar mass of iron (Fe) is 55.85 g/mol, which can be found on the periodic table. Using this information, we can set up a conversion factor to convert grams to moles.
Step 1: Convert grams to moles using the molar mass of iron.
Number of moles = mass of iron (g) / molar mass of iron (g/mol)
For a paper clip weighing 1 gram:
Number of moles = 1g / 55.85 g/mol = 0.0179 moles of iron
This calculation assumes that the paper clip is made entirely of iron, which is a reasonable approximation for most standard paper clips.
