Entropy of formation?

  1. May 31, 2010 #1
    the standard entropy of formation of magnesium is 32.7 J/mol k , That of oxygen gases 205.2 J/mol k

    at that magnesium oxide is 26.9 J/mol k .

    A) What is the entropic energy change when 25 grams of magnesium are burned inexcess oxygen at 25 celsius ??

    B) Does the burning of magnesium in oxygen lead to increase or decrease in entropy in the system ??

    I hope the solution step by step ..

    regards ^_^ ..

    You should probably go post this in the homework section.
