Question

Please help me with this chemistry homework thank you so much

Answer 1

Step-by-step explanation:

We are given: Pressure of Xe gas = 0.607 atm

: Temperature of Xe gas = 24 degrees Celsius

: Volume of Xe gas = 22.1 L

Temperature Xe gas in Kelvins = 24.0 + 273 = 297 K

We know: Ideal gas constant = 0.082 L.atm/K.mol

To find the number of moles of Xe gas, we use the ideal gas law:

`\begin{gathered} PV\text{ = nRT} \\ \\ \therefore n\text{ = }(PV)/(RT) \\ \\ \text{ = }(0.607*22.1)/(0.082*297) \\ \\ \text{ = 0.55 mol} \end{gathered}`

Answer:

The number of moles of Xe gas present is 0.55 mol.
