SUMMARY

The discussion focuses on calculating the mass of a piston and the height of an ideal gas column in a vertical cylindrical tank. Given the parameters of the tank, including a volume of 1.75 m³, pressure of 1.00 atm, and temperature of 20.0°C, the height of the gas column was correctly calculated as 1.34 meters. However, participants noted the absence of units in the problem statement, which hindered the calculation of the piston mass using the ideal gas law equation, PV=nRT.

PREREQUISITES
  • Understanding of the Ideal Gas Law (PV=nRT)
  • Knowledge of pressure, volume, and temperature units
  • Familiarity with basic physics concepts related to gas behavior
  • Ability to perform unit conversions and dimensional analysis
NEXT STEPS
  • Research the application of the Ideal Gas Law in real-world scenarios

Homework Statement



A vertical cylindrical tank contains 1.75 of an ideal gas under a pressure of 1.00 at 20.0. The round part of the tank has a radius of 10.0 , and the gas is supporting a piston that can move up and down in the cylinder without friction.
What is the mass of this piston?
How tall is the column of gas that is supporting the piston?

Homework Equations



pv=nrt

The Attempt at a Solution

for the 2nd question i got h=1.34m and that answer is correct. I have no clue how to find the mass of the piston using pv=nrt.
