<h3>
Answer:</h3>
112.08 mL
<h3>
Explanation:</h3>
From the question we are given;
- Initial volume, V1 = 100.0 mL
- Initial temperature, T1 = 225°C, but K = °C + 273.15
thus, T1 = 498.15 K
- Initial pressure, P1 = 1.80 atm
- Final temperature , T2 = -25°C
= 248.15 K
- Final pressure, P2 = 0.80 atm
We are required to calculate the new volume of the gases;
- According to the combined gas law equation;

Rearranging the formula;

Therefore;


Therefore, the new volume of the gas is 112.08 mL
