Sulfuric acid weighing 9.8 g reacted with zinc. Determine the amount of gas evolved.

Let’s implement the solution:
1. Write down the equation:
Zn + H2SO4 = ZnSO4 + H2 – substitution reaction, hydrogen gas is released;
Determine the molar masses of substances:
M (H2SO4) = 98 g / mol;
M (H2) = 2 g / mol.
We calculate the amount of moles of sulfuric acid, if its mass is known:
Y (H2SO4) = m / M = 9.8 / 98 = 0.1 mol;
Y (H2) = 0.1 mol since in the equation the amounts of these substances are equal to one mol.
Find the volume of the reaction product – H2:
V (H2) = 0.1 * 22.4 = 2.24 liters.
Answer: during the reaction, hydrogen with a volume of 2.24 liters was formed.
