How many balloons of capacity 2.0 dm³ can be filled at 1 atm and 27°C by using the gas effused out i — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Moles effused = $\Delta P \times V / RT = 18.5 \times 10 / RT = 185/RT$. Balloon moles = $1 \times 2 / RT = 2/RT$. Number of balloons = $185 / 2 = 92.5$. Thus 92 balloons. Therefore, correct answer is B.
