Calculate the mass of acetic acid reacted with zinc if 11.2 liters of hydrogen have been released.

When dissolved in acetic acid, metallic zinc is converted to zinc acetate.

Zn + 2CH3COOH = Zn (CH3COO) 2 + H2;

Let’s calculate the chemical amount of hydrogen. For this purpose, we divide its volume by the volume of 1 mole of gas (which is 22.4 liters).

N H2 = 11.2 / 22.4 = 0.5 mol;

To obtain this amount of hydrogen, you need twice as much acetic acid.

Let’s calculate its weight. To do this, multiply the molar amount of acid by the weight of 1 mol of acid.

M CH3COOH = 60 grams / mol;

m CH3COOH = 0.5 x 2 x 60 = 60 grams;
