Determine the mass of the formed salt, if it is known that zinc, weighing 260 g. reacted with sulfuric acid.
October 8, 2021 | education
| When zinc is dissolved in sulfuric acid, zinc sulfate is formed. It has the following chemical formula ZnSO4. From 1 mole of zinc it is possible to synthesize 1 mole of its sulfate.
Let’s calculate the chemical amount of a substance contained in 26 grams of zinc.
M Zn = 65 grams / mol;
N Zn = 260/65 = 4 mol;
The same amount of zinc sulfate will be synthesized.
Let’s calculate its weight.
M ZnSO4 = 65 + 32 + 16 x 4 = 161 grams / mol;
m ZnSO4 = 161 x 4 = 644 grams;
