I think it should be 4, two for each carbonyl. 


But in mybook it is given as 7 .




In the given compound 
1) grignard reagent will act as a nucleophile and attack twice on both carbonyl groups. So 4 moles here 
2) it will act as a base and react with the phenol, thiol, and chloride group. So 3 moles here 
Therefore a total of 7 moles will be required
