A sample of 500 mL Ne gas is at 0.868 atm and 55 C. What is the new volume if the pressure is increased to 1.35 atm and the temp
WITCHER [35]
<h3>Answer:</h3>

292.10 mL

<h3>Explanation:</h3>

From the question we are given;

  • Initial volume, V1 of Ne gas is 500 mL
  • Initial pressure, P1 of Ne gas is 0.868 atm
  • Initial temperature, T1 of Ne gas is 55°C
  • but, K = °C + 273.15, thus, T1 = 328.15 K
  • Final pressure of the gas, P2 = 1.35 atm
  • Final temperature of the gas, T2 = 25°C

                                                              = 298.15 K

We are required to calculate the new volume, V2 of the gas;

Using the combined gas equation;

\frac{P1V1}{T1}=\frac{P2V2}{T2}

Rearranging the formula we can calculate the new volume, V2;

V2=\frac{P1V1T2}{P2T1}

V2=\frac{(0.868atm)(500mL)(298.15K|)}{(1.35atm)(328.15K)}

V2=292.10mL

Therefore, the new volume is 292.10 mL
