The molar mass of hydrogen (H) is 1 g/mol, the molar mass of chlorine (Cl) is 35 g/mol, and the molar mass of zinc (Zn) is 65 g/mol. When 130 grams of zinc react completely in hydrochloric acid (HCl), how much is the total mass of the products

Respuesta :

Oseni

The total mass of the product will be 137 grams.

Stoichiometric calculations

From the equation of the reaction:

[tex]Zn + 2HCl --- > ZnCl_2 + H_2[/tex]

Mole of 130 grams of Zn = 130/65 = 2 moles

Equivalent mole of [tex]ZnCl_2[/tex] = 1 mole = 1 x135 = 135 grams

Equivalent mole of [tex]H_2[/tex] = 1 mole = 1 x 2 = 2 grams

Total mass of the products = 135 + 2 = 137 grams.
