Answer:</h3>
24.94 L
<h3>
Explanation:</h3>
<u>We are given;</u>
- Moles of Helium, n= 1 mole
- Pressure of the gas, P = 100 kPa
- Temperature of the gas, T = 300 K
We are required to calculate the volume of the balloon
- We are going to use the ideal gas equation;
- According to the ideal gas equation;
PV = nRT , where R is the ideal gas constant, 8.314 L.kPa/mol.K
V = nRT ÷ P
= ( 1 × 8.314 × 300 K) ÷ 100 kPa
= 24.94 L
Therefore, the volume of the balloon is 24.94 L
