The same way you calculate the molecular mass of any compound.

Alternatively, if you know the mass of one isomer, you don't need to do any calculations. All isomers having the same formula have the same mass.

Are alpha and beta glucose structural isomers?

no they are not. they are stereoisomers(configurational) Structural isomers. isomers that differ in the arrangement literally. so the difference between the cylic glucose molecule that is a ring and the non ring glucose. these two are structural isomers. if molecule A and B have the same molecular formula but look different and are thus arranged differently they are structural isomers. conformational isomers. these are isomers that differ from each other simply by the rotation around a single bond. if molecule B can be twisted around the single bonds to get molecule A then A and B are conformational isomers. configurational isomers (stereoisomers). if molecules A and B do not fall into the above two categories, then they are stereoisomers. these type of isomers differ in the spatial arrangement of atoms. so if molecule A was the mirror image of molecule B then these two molecules would be a type of stereoisomers called (Enantiomers). for alpha glucose the OH group attached to the anomeric carbon is not the same as teh CH2OH group on the other side of the hemiacetal( on the other side of the ether oxygen.). ie. if the OH is axial down then the CH2OH is equatorial up. and vice versa. the molecule is beta glucose when these two substituents are the same in this aspect. both either equatorial or axial. the difference between axial and equatorial is spatial adn in the arrangement of atoms connected to the carbon ring and solely a difference in this aspect (alpha or beta) means the molecules are stereoisomers.
