Question

in the given question on fe2o3, the number of moles of fe atoms is _ and moles of oxygen atoms is _
a 0.762, 2.29
b 0.762, 0.762
c 1.525, 2.29
question 3 of 4

Explanation:

Step1: Analyze the formula of Fe2O3

In one - mole of Fe2O3, there are 2 moles of Fe atoms and 3 moles of O atoms.

Step2: Assume the number of moles of Fe2O3 is 0.762 moles

If the number of moles of Fe2O3 is 0.762 moles, then the number of moles of Fe atoms is \(n_{Fe}=2\times0.762 = 1.524\approx1.525\) moles.

Step3: Calculate moles of O atoms

The number of moles of O atoms is \(n_{O}=3\times0.762=2.286\approx2.29\) moles.

Answer:

C. 1.525, 2.29
