Calculate the missing variable in the following experiment using Avogadro's law: V₁ = 4.20 L, n₁ = 0.753 mol, V₂ = 2.93 L, n₂ = ?

Question

Quizplus · Accepted Answer

Avogadro's law states that the volume of a gas at constant temperature and pressure is directly proportional to the number of moles of the gas. Therefore, $V_1/n_1 = V_2/n_2$. Substituting the given values: $4.20\,L / 0.753\,mol = 2.93\,L / n_2$. Solving for $n_2$ gives $n_2 = (2.93\,L \times 0.753\,mol) / 4.20\,L = 0.525\,mol$.
