Question

How many moles are in 223.2 g iron (Fe)?

a. 55.8 moles
b. 223.2 moles
c. 26 moles
d. 4 moles

Answer 1

To find the number of moles in 223.2 g of iron (Fe), divide the given mass by the molar mass of iron, which is 55.8 g/mol. The correct answer is d. 4 moles.

Step-by-step explanation:

To find the number of moles in 223.2 g of iron (Fe), we need to use the molar mass of iron. The molar mass of iron is 55.8 g/mol. To calculate the number of moles, divide the given mass by the molar mass:

Number of moles = mass / molar mass

Number of moles = 223.2 g / 55.8 g/mol = 4 moles

Therefore, the correct answer is d. 4 moles.
