Given:
V (C2H6) = 7.5 L
To find:
V (H2) =?
Solution:
1) Let’s compose the equation of the chemical reaction, let the hydrogen be x l.
C2H6 = C2H4 + H2
2) Vm is a constant value and is equal to 22.4 l / mol.
3) 7.5 L: 22.4 L / mol = x L: 22.4 L / mol
x = (7.5 x 22.4 L / mol): 22.4 L / mol = 7.5 L
Answer: V (H2) = 7.5 liters.
