SUMMARY

The volume of 1 mol of steam at 100°C and 1 atm can be calculated using the Ideal Gas Law equation, PV=nRT. By rearranging the equation to solve for volume (V), and substituting the values for pressure (P = 1 atm), the number of moles (n = 1 mol), the ideal gas constant (R = 0.0821 L·atm/(K·mol)), and temperature (T = 373.15 K), the calculation yields a volume of approximately 24.79 liters. This confirms that the initial approach of rearranging the equation and substituting the values is indeed correct.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV=nRT)
  • Knowledge of unit conversions (Celsius to Kelvin)
  • Familiarity with basic algebra for rearranging equations
  • Concept of moles in chemistry
NEXT STEPS
  • Study the Ideal Gas Law applications in real-world scenarios
  • Learn about deviations from ideal gas behavior in real gases
  • Explore the significance of temperature and pressure in gas laws
  • Investigate the properties of steam and its phase changes
USEFUL FOR

Chemistry students, educators, and anyone interested in thermodynamics and gas laws will benefit from this discussion.

Homework Statement


Calculate the volume of 1 mol of steam at 100°C and a pressure of 1 atm assuming that it is an ideal gas.

Homework Equations


PV=nRT

The Attempt at a Solution


Well, if I am honest I was just going to re arrange the above equation for V and plug the numbers in but that seems far too easy so I assume I am wrong.

Can someone clarify that I am wrong and just give a gentle push in the right direction please?

Thank you!

Assume so.

Assume so.

I did that when I said I would use PV=nRT though?

Your approach is correct. Start plugging.
