A tank with a volume of 658 mL contains 1.50 g of neon gas. The maximum safe pressure that
the tank can withstand is 450 kPa. At what temperature will the tank have that pressure

Answer:

206°C

Explanation:

To solve this question we must use the combined gas law:

PV = nRT

Where P is pressure in atm, V is volume in liters, T absolute temperature, n are moles of gas, and R gas constant.

Pressure:

450kPa * (1atm / 101.325kPa) = 4.441atm

Volume:

658mL = 0.658L

Moles -Molar mass Ne: 20.1797g/mol-

1.50g * (1mol / 20.1797g) = 0.07433 moles

R: 0.082atmL/molK

Replacing to solve T:

T = PV/nR = 4.441atm*0.658L / 0.07433 moles*0.082atmL/molK =

T = 479K

In °C:

479K -273 =

206°C
