Answer 3

Ba(OH)2 is a molecular formula. It is called Barium Hydroxide.

The molecular mass is 171.3388. You achieve this answer by adding the molar masses of each element in the formula. You add the molar masses of oxygen and hydrogen twice because there is a subscript of 2 on the OH.

Hope this helps :)
