Question

  What is the pressure in atm exerted by 2.48 moles of a gas in a 250.0 mL container at 58 C?

I'm so lost with this problem. can someone give me a step by step to getting the answer

thank you

Answer 1

To solve for this you would need to use the ideal gas law; PV=nRT.

1. P = pressure (Pascals)
2. V = volume (liters)
3. n = number of moles
4. R = gas constant (8.314 J/(K*mol) )
5. T = Temperature in Kelvin

In order to find the pressure, you need to convert 58 C to Kelvin, 250mL to Liters, and use the gas constant, rearrange, and solve.

Once you have your answer it will be in Pascals, and you can use a conversion factor to get your answer in atmospheres.

Does this help?
