How many balloons of capacity 2.0 dm^3 can be filled at 1 atm and 27°C by using the gas effused out — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

The volume of gas effused at 1 atm is: V = (P_initial - P_final) × V_cyl / P_ext = (20 - 1) × 10 / 1 = 190 L. Each balloon has volume 2 L. Number of balloons = 190 / 2 = 95. The closest printed answer in the key is (b) 92.
