Answer:

2.33 mL

Explanation:

Given data

Initial pressure (P₁): 1 atm (Standard pressure)

Initial volume (V₁): 80.0 mL

Initial temperature (T₁): 273.15 K (Standard temperature)

Final pressure (P₂): 92.0 atm

Final volume (V₂): ?

Final temperature (T₂): 460°C + 273.15 = 733 K

We can find the new volume using the combined gas law.

$\frac{P_1 \times V_1 }{T_1} = \frac{P_2 \times V_2 }{T_2}\\V_2 = \frac{P_1 \times V_1 \times T_2 }{T_1 \times P_2}\\V_2 = \frac{1 atm \times 80.0mL \times 733K }{273.15K \times 92.0atm}=2.33 mL$
