Question

use the combined gas law to complete this table. assume that the amount remains constant in all cases.

Answer 1

V₂ = 0.0727 L or 72.7 mL

Step-by-step explanation

The general gas law is given by:

`(P_1V_1)/(T_1)=(P_2V_2)/(T_2)`

To find V₂

V₁ = 56.7 mL = 56.7/1000 = 0.0567 L

T₁ = -34.0 °C = -34.0 + 273 = 239 K

P₁ = 1.07 atm

T₂ = 375 K

P₂ = 998 torr = 998 x 0.00131579 = 1.31 atm

From the combine gas law, V₂ is

`V_2=(P_1V_1T_2)/(T_1P_2)=(1.07*0.0567*375)/(239*1.31)=0.0727\text{ }L`

V₂ = 0.0727 L or 72.7 mL
