Question 1 of 10

How many moles are in 223.2 g iron (Fe)?
O A. 26 moles
O B. 4 moles
OC. 55.8 moles
O D. 223.2 moles

Answer 1

The number of moles in 223.2 g of iron (Fe) is 4 moles.

Step-by-step explanation:

To find the number of moles in iron (Fe), we need to use the molar mass of iron. The molar mass of Fe is 55.8 g/mol. We can use the formula:

moles = mass / molar mass

Substituting the given mass of 223.2 g and the molar mass of Fe, we get:

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

Therefore, there are 4 moles in 223.2 g of iron (Fe).
