Finding mass using pv=nrt

Finding mass using pv=nrt: "
1. The problem statement, all variables and given/known data



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?

2. Relevant equations



pv=nrt



3. 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.
