The mass of barium chloride produced is 21.6 grams.
It is an inorganic compound with the chemical formula BaCl₂.
The equation: HCl + barium --> barium chloride + hydrogen
The chemical equation : 2HCl + Ba --> BaCl₂ + H₂
Given the 1.25×10²³ molecules HCl
First, we calculate the amount of HCL
Amount of moles of HCl=
(1.25×10²³ molecules × 1 mole)/ 6.023×10²³ atoms
=0.2075 moles.
Then the number of moles is multiplied by the molar mass of barium chloride
208.24 g/mol × 0.2075 = 21.6 grams.
Thus, the mass of barium chloride produced is 21.6 grams.
