Question

Formula mass of hydrated magnesium oxide

Answer 1

Hydrated Magnesium Oxide = Mg(OH)2

(The compound produce on hydration of Magnesium Oxide)

Formula mass of Mg(OH)2 

= Atomic mass of Mg + 2 × ( atomic mass of oxygen + atomic mass of Hydrogen)

= [ 24.3 + 2 × ( 16 + 1 ) ] g/mole

= 58.3 g/ mole

Hence, formula mass of Hydrated Magnesium Oxide = 58.3 g/ mole
