To find number of moles, divide mass (in grams) by molecular weight.
Molecular weight of Ba(OH)2 = 171.3438 grams/mole.
100.0 grams / 171.34 grams/mole = 0.5836219344 moles.
0.583 moles.

It would be the atomic mass of Ba + 2*17 (O+H), all divided into 100.

Use Gram Mole Weight
1 mole Ba(OH)2 = 171.34468 grams
171.34468 grams = 137.33 grams Ba + 2(15.9994) grams O + 2(1.00794) grams H
100.0g(1 mole/171.34468 grams) = 0.5836 moles Ba(OH)2 [4SF]
That should be it...

100 g/(137.3 + 2*(16 + 1.008)) g/mol = 0.5837166 mole
