For the reaction 2 HCl + Ca ( OH ) 2 ⟶ CaCl 2 + 2 H 2 O how many grams of calcium hydroxide, Ca(OH)2, are needed to react completely with 57.7 g of hydrochloric acid, HCl?

58.53 g of is need to react completely with 57.7 g of HCl.

Explanation:

Mass of HCl = 57.7g

Molecular mass of HCl= 36.46g/mol

Mass mass of = 74.09g/mol

Calculationg mass of HCl,

moles

As per the given equation,

mol HCl mol

1.58 moles mol

Now, calculating mass of from the above calculated moles,

mass of

mass of .
