Step 1: State the approximate percentage of noble gases in air.
Noble gases (like Argon, Neon, Helium, Krypton, and Xenon) constitute approximately 1% of the volume of air.
Step 2: Set up the equation to find the original volume of air.
Let $V$ be the original volume of air.
The volume of noble gases obtained is 25 cm³.
So, 1% of the original volume of air is 25 cm³.
$$0.01 \times V = 25 \text{ cm}^3$$
Step 3: Solve for V.
$$V = \frac{25 \text{ cm}^3}{0.01}$$
$$V = 2500 \text{ cm}^3$$
The original volume of air was 2500 cm³.
