You have a 4.0 L steel tank containing hydrogen gas. You are able to heat or cool the tank, and measure the pressure of the gas.
If the temperature is 25 degrees C, and the pressure reads 2.5 atm, how many grams of hydrogen does the tank contain?
Is 9.8 the correct answer

9.8 won't do it.
Show your work and I'll find the error.
