Question

If an ideal gas has a pressure of 2.65 atm, a temperature of 92.55 °C, and has a volume of 51.43 L, how many moles of gas are in the sample?

Answer 1

Approx. `4.5*mol`

Explanation:

From the Ideal Gas Equation:

`n=(PV)/(RT)` `=` `(2.65*atmxx51.43*L)/(0.0821*L*atm*K^-1*mol^-1xx365.7K)`

The Ideal Gs Equation requires absolute temperature values: `T("Kelvin")=T(""^@Celsius + 273.15)`.
