Understanding the Concepts

* STP (Standard Temperature and Pressure): This refers to a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere.

* Molar Volume: At STP, one mole of any ideal gas occupies 22.4 liters.

Calculations

1. Moles in 224 liters:

* Since 22.4 liters is equal to 1 mole, then 224 liters contains 224 / 22.4 = 10 moles.

2. Moles in 560 liters:

* If 22.4 liters contain 1 mole, then 560 liters contain 560 / 22.4 = 25 moles.

Therefore, there are 25 moles of gas in a balloon containing 560 liters at STP.
