How do you get molar mass?

50g Fe[sub]2[/sub]O[sub]3[/sub] x 1mol/159.7g x 6HCl& & & /& & & & 1Fe[sub]2[/sub]O[sub]3[/sub] x 36,46g/1mol =68.49g HCl

the balanced chemical equation is given Fe[sub]2[/sub]O[sub]3[/sub] + 6HCl --> 2FeCl[sub]3[/sub] + 3H[sub]2[/sub]O

Where does the 159.7g come from ??
