Question

How many moles of H2O will be produced from 12.3 moles of HCl reacting with Ca(OH)2?

Answer 1

Solution.

$\nu$ (HCl) =12.3 mol;

$\nu$ ( H₂O) -?;

2HCl + Ca(OH)₂ $\to$ CaCl₂ + 2H₂O;

12.3 mol --------------------------x mol;

2 ------------------------------2;

x = (12.3 mol x 2)/2 =12.3 mol;

Answer: $\nu$( H₂O) =12.3 mol.
