Calculate the mass of zinc that will be required to react with 9.8 g of sulfuric acid.

Let’s implement the solution:
1. In accordance with the condition, we write down the equation of the process:
Zn + H2SO4 = ZnSO4 + H2 – substitutions, hydrogen is evolved;
2. Let’s make the calculations:
M (Zn) = 65.3 g / mol.
M (H2SO4) = 98 g / mol.
Y (H2SO4) = m / M = 9.8 / 98 = 0.1 mol.
Y (Zn) = 0.1 mol since the amount of substances is 1 mol.
3. Find the mass of the original substance:
m (Zn) = Y * M = 0.1 * 65.3 = 6.53 g.
Answer: the mass of zinc is 6.53 g.
