To test the effectiveness of a gunpowder mixture, 1 gram was exploded under controlled stp conditions, and the reaction chamber was found to expand to 310 cm3. what volume would these gases occupy at the temperature produced by an uncontrolled explosion (2,200°c) and 2.1 atmospheres of pressure?

1.3 × 10³ cm³

Explanation:

The gas occupies a volume of V₁ = 310 cm³ under standard temperature and pressure (STP), that is, T₁ = 273.15 K and P₁ = 1.0 atm. In order to find the volume V₂ under different conditions we can use the combined gas law formula.
