Answer:
4.33 L
Explanation:
Step 1: Given data
Initial volume of the balloon (Vā): 3.00 L
Initial pressure of the balloon (Pā): 765 torr
Final Ā volume of the balloon (Vā): ?
Final pressure of the balloon (Pā): 530 torr
Step 2: Calculate the final volume of the balloon
If we consider Helium to behave as an ideal gas, we can calculate the final volume of the balloon using Boyle's law.
[tex]P_1 \times V_1 = P_2 \times V_2\\V_2 = \frac{P_1 \times V_1}{P_2} = \frac{765torr \times 3.00L}{530torr} = 4.33 L[/tex]
