Chemistry problem: find the volume of HCl obtained by the interaction of 15 liters of chlorine

Chemistry problem: find the volume of HCl obtained by the interaction of 15 liters of chlorine (gas) with hydrogen (H) Formula H2 + Cl2 = HCl.

Given:
V (Cl2) = 15 l

To find:
V (HCl) -?

Solution:
1) Write the equation of a chemical reaction:
H2 + Cl2 => 2HCl;
2) Calculate the volume of hydrogen chloride according to the Gay-Lussac law (the law of volumetric ratios):
V (HCl) = V (Cl2) * 2 = 15 * 2 = 30 liters.

Answer: The volume of HCl is 30 liters.
