How many atoms are in Ba OH 2?

Answer 1

1 mol Ba X (137.33 g Ba / mol Ba) = 137.33 g Ba

2 mol O X (16.00 g O / mol O) = 32.00 g O

2 mol H X (1.01 g H / mol H) = 2.02 g H

Molar mass of Ba(OH)2 = 171.35 g/mol

Answer 2

'baOH' does not make 'chemical' sense.

The formula weight of barium hydroxide, Ba(OH)2 , is

• 171.34 g/mol (anhydrous, Ba(OH)2 )
• 189.39 g/mol (monohydrate, Ba(OH)2.(H2O) )
• 315.46 g/mol (octahydrate, Ba(OH)2.(H2O)8 )
