Is my calculations correct?. Yellow is observations which are known. White is my calculations.

Consider the reaction: 2H₂O(1) 2H₂(g) + O₂(g) Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 1.81 moles of H₂O(1) react at standard conditions. AS° surroundings = J/K
