Answer:
.01
Step-by-step explanation:
moles = mass / molar mass
mass of Fe = 0.56 g
molar mass of Fe = 55.85 g/mol
moles = 0.56 g / 55.85 g/mol
moles = 0.01 mol (rounded to two decimal places)
Therefore, 0.56 g of pure Fe is equal to 0.01 moles.
Moles of Pure Iron: 0.01
Synopsis: This question is asking how many moles of pure iron (Fe) are present in a sample that weighs 0.56 grams.
Numbered list format:
The question is asking about the number of moles of Fe in a sample.
The sample weighs 0.56 grams.
We need to calculate the number of moles using the formula: moles = mass/molar mass.
The molar mass of Fe is 55.85 g/mol.
Plug in the values to the formula: moles = 0.56 g / 55.85 g/mol.
Simplify the expression: moles = 0.01 mol.
Simple analogy: If you have a bag of 10 marbles and each marble weighs 1 gram, and you want to know how many marbles are in a bag that weighs 0.56 grams, you would divide the weight of the bag (0.56 grams) by the weight of one marble (1 gram) to find the number of marbles in the bag (0.56 marbles).
Summary: The question asks for the number of moles of pure Fe in a sample of 0.56g, which can be calculated by dividing the mass by the molar mass of Fe, giving a result of 0.01 mol.
The answer is 0.01 moles.

what is the answer
The answer is 0.01 moles.
show the math
Sure, here's the math:
moles = mass / molar mass
mass of Fe = 0.56 g
molar mass of Fe = 55.85 g/mol
moles = 0.56 g / 55.85 g/mol
moles = 0.01 mol (rounded to two decimal places)
Therefore, 0.56 g of pure Fe is equal to 0.01 moles.
