The new volume of the gas is 966 mL
Explanation:
Step 1: Data given
Volume = 535 mL
Initial temperature = -25.0 °C
Final temperature = 175 °C
Step 2: Calculate the new volume
V1/T1 = V2/T2
⇒with V1 = the initial volume = 535 mL = 0.535 L
⇒with T1 = -25 °C = 248 K
⇒with V2 = the new volume = TO BE DETERMINED
⇒with T2 = the new temperature = 175 °C = 448K
0.535 L/ 248 K = V2 / 448K
V2 = 0.966 L =966 mL
The new volume of the gas is 966 mL
