Answer:
The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process . The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure. (Below are listed tips)
- At absolute zero (0 K), the entropy of a pure, perfect crystal is zero.
- The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process.
- The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure.

Answer:
26.81 moles
Explanation:
From the coefficients of the equation, we know that for every 2 moles of iron(III) oxide produced, 7 moles of oxygen are consumed.
So, the answer is 7.66(7/2), which is 26.81 mol.
