Question

At what pressure would a 0.175 mole sample of gas at 22.0°C have a volume of 2175
mL?

Answer 1

`P=1.95atm`

Step-by-step explanation:

Hello!

In this case, since we are asked to compute the pressure of 0.175 moles of the given gas at 22.0 °C occupying a volume of 2175 mL, we can use the ideal gas equation as shown below:

`PV=nRT`

Whereas our unknown is P and we solve for it as shown below:

`P=(nRT)/(V)\\ \\P=(0.175mol*0.082(atm*L)/(mol*K)*(22.0+273.15)K)/(2175mL*(1L)/(1000mL) )\\ \\P=1.95atm`

Take into account that based on the given R units, the temperature must be in Kelvins and the volume in liters.

Best regards!
