According to the equation below, if 2.00 g of PCl5 react completely, how many grams of HCl will be produced?


PCl5+4H2O→H3PO4+5HCl


Sagot :

Answer:

1.75 g HCl

Explanation:

  • PCl₅ + 4H₂O → H₃PO₄ + 5HCl

First we convert 2.00 g of PCl₅ into moles, using its molar mass:

  • 2.00 g ÷ 208.24 g/mol = 0.0096 mol PCl₅

Then we convert PCl₅ moles into HCl moles, using the stoichiometric coefficients of the equation:

  • 0.0096 mol PCl₅ * [tex]\frac{5molHCl}{1molPCl_5}[/tex] = 0.048 mol HCl

Finally we convert HCl moles into grams, using its molar mass:

  • 0.048 mol HCl * 36.45 g/mol = 1.75 g HCl
