A 10.0L gas cylinder is filled with 9.40moles of gas. The tank is stored at 47∘C . What is the pressure in the tank
This is an ideal gas law problem! The equation you want to use is known as: PV=nRT
P=pressure V=volume n=# of moles R=ideal gas constant (8.31447 JKmol) and T= temp in K. Convert 47 to Kelvin by adding 271.15 to 47.0 and convert 10L to mL and solve for P!
