How many moles of Magnesium Hydroxide can be expected from 0.01246 moles MgSO4?

Answer 1

Do you mean from this reaction?

MgSO4 + 2H2O -> Mg(OH)2 + H2SO4

let us assume water is in excess

0.01246 MgSO4 (1 mole Mg(OH)2/1 mole MgSO4)

= 0.01246 moles Mg(OH)2 produced

-----------------------------------------------

This reaction is one to one.

Answer 2

To find the moles of Mg(OH)2 produced, we need to consider the stoichiometry of the reaction. In the balanced chemical equation, there is a 1:1 molar ratio between MgSO4 and Mg(OH)2. Therefore, 0.01246 moles of MgSO4 will produce 0.01246 moles of Mg(OH)2.
