Question

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

Answer 1

Answer

V₂ = 0.0727 L or 72.7 mL

Explanation

The general gas law is given by:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

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

$V_2=\frac{P_1V_1T_2}{T_1P_2}=\frac{1.07\times0.0567\times375}{239\times1.31}=0.0727\text{ }L$

V₂ = 0.0727 L or 72.7 mL
