Mass gain due to incorporation of one acetyl group = 59 - 17 = 42
Net mass gain due to acetylation = 518 - 266 = 252
Hence, six hydroxy groups (6 x 42 = 252) were present.

Explanation:
- Compound A has the molecular formula C10H18O8.
- On treatment with excess CH3COCI, it gives a fully acetylated product.
- The molar mass of the fully acetylated product is found to be 518 g/mol.
- We need to determine the number of hydroxyl functional groups present in compound A.
- The molar mass of the fully acetylated product (518 g/mol) indicates that all the hydroxyl groups in A have been replaced by acetyl groups.
- The molecular formula of the fully acetylated product can be written as C10H10O8.
- The difference in molar mass between A and its fully acetylated product is due to the presence of hydroxyl groups in A.
- The molecular weight of the acetyl group is 43 g/mol.
- The difference in molar mass between A and its fully acetylated product is (518 - (10 x 43) = 78 g/mol.
- There are six hydroxyl groups in A because the molecular weight of each hydroxyl group is 17 g/mol (10 x 17 = 170 g/mol), and the difference in molar mass between A and its fully acetylated product is 78 g/mol.
