Convert temperature to Kelvin

  • 225°C=498K
  • 127°C=400K

Convert vol to L

  • 400mL=0.4L

Apply Charles law

  • V1T_2=V2T_1
  • 0.4(400)=498V_2
  • 160=498V_2
  • V_2=0.32L=320mL

Answer:

<h3>Given:</h3>

V_{1} = \text{400.0 mL}

T_{1} = 225.0^{\circ}\text{C + 273.15 = 498.15 K}

T_{2} = 127.0^{\circ}\text{C + 273.15 = 400.15 K}

<h3>Unknown:</h3>

V_{2}

<h3>Solution:</h3>

\dfrac{V_{1}}{T_{1}} = \dfrac{V_{2}}{T_{2}}

V_{2} = V_{1} \times \dfrac{T_{2}}{T_{1}}

V_{2} = \text{400.0 mL} \times \dfrac{\text{400.15 K}}{\text{498.15 K}}

\boxed{V_{2} = \text{321.3 mL}}

Therefore, the volume of the gas at 127.0°C is 321.3 mL
